Product details
Overview
MIC22600YTSE-TR from Microchip Technology is a 6A, 1 MHz synchronous buck regulator with integrated high-side P-channel and low-side N-channel MOSFETs, adjustable output down to 0.7V, input range 2.6V–5.5V, and full sequencing/tracking capability for multi-rail FPGA and ASIC power systems.
For engineers reviewing the MIC22600YTSE-TR datasheet, MIC22600YTSE-TR pinout, MIC22600YTSE-TR application, or MIC22600YTSE-TR equivalent, this page delivers verified specifications, thermal performance data, RC/DELAY sequencing behavior, and real-world transient response metrics - all confirmed for the 24-pin ePad TSSOP (TSE) package variant.
Technical Context
The MIC22600YTSE-TR implements voltage-mode PWM control with a fixed 1 MHz oscillator, internal 0.7V reference, and adaptive gate drive optimized for ceramic-capacitor-based point-of-load designs. Its control loop integrates a fixed-frequency zero and pole to simplify external compensation using only one resistor and capacitor on the COMP pin.
Sequencing is enabled via three dedicated pins: EN/DLY (1 µA current source, 1.24V threshold), DELAY (1 µA source/sink for matched rise/fall timing), and RC (1 µA programmable slew rate control). These support precise up/down sequencing and ratio-metric tracking between multiple MIC22600YTSE-TR units or across MIC22xxx/MIC68xxx families.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.6V to 5.5V - supports single-supply operation from common logic rails (3.3V, 5V) without external LDO pre-regulation. |
| Output Current | Up to 6A continuous - sufficient for core voltage of mid-tier FPGAs (e.g., Xilinx Artix-7, Intel Cyclone V) and low-voltage ASICs. |
| Switching Frequency | 1 MHz ±20% - enables compact 1 µH inductor + 47 µF ceramic output filter; avoids AM radio band interference. |
| Feedback Reference | 0.7V ±1% - sets output as low as 0.7V with standard resistor divider; stable over –40°C to +125°C junction range. |
| Efficiency | >90% at 1.8V/6A, VIN = 3.3V - achieved via 30 mΩ P-FET and 25 mΩ N-FET RDS(on), minimizing conduction loss at full load. |
| Thermal Resistance | θJA = 32.2°C/W (TSSOP ePad) - enables 6A operation at +85°C ambient with minimal PCB copper area (≥2 in² GND plane). |
| Protection Features | Thermal shutdown (160°C), cycle-by-cycle current limit (9A typ), and open-drain POR/PG with 10% hysteresis - ensures safe fault recovery without latch-up. |
Pinout & Package
Package: 24-pin thermally enhanced ePad TSSOP (TSE), 0.65 mm pitch, exposed thermal pad (EP) requiring full-solder connection to PCB ground plane for rated 6A operation and optimal θJA = 32.2°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PVIN (Pins 3,10,15,22) | Power Input Supply | Bypassed separately per pin with ≥10 µF X5R/X7R ceramic; supplies high-side P-MOSFET; shared with SVIN externally. |
| SVIN (Pin 2) | Signal Input Supply | Provides bias for internal logic and error amplifier; must be connected to PVIN; bypassed with 10 µF ceramic. |
| EN/DLY (Pin 11) | Enable & Startup Delay Control | 1 µA current source charges external capacitor; device enables at 1.24V; delay time = 1.24V / 1 µA × CDLY. |
| RC (Pin 13) | Ramp Control | 1 µA current source/sink programs output voltage slew rate during startup/shutdown; enables tracking with other MIC22xxx devices. |
| FB (Pin 23) | Feedback Input | Connects to resistor divider; compares against 0.7V internal reference; max input current 100 nA minimizes divider error. |
| COMP (Pin 24) | Compensation Node | External RC network (e.g., 20 kΩ + 15 pF) sets dominant pole-zero pair; stabilizes loop with 1 µH inductor + 47 µF ceramic output. |
| POR/PG (Pin 21) | Power-On Reset Output | Open-drain signal asserted high when VOUT ≥ 90% nominal after DELAY timeout; pulled up externally (e.g., 47 kΩ to SVIN). |
| DELAY (Pin 12) | Power-Good Timing Delay | 1 µA source/sink controls POR assertion/deassertion delay; matched rise/fall timing enables "first-up, last-down" sequencing. |
| SW (Pins 5,6,7,8,17,18,19,20) | Switch Node | Drain connection of internal P-FET and N-FET; high di/dt node requiring short, wide PCB traces and local 100 nF ceramic decoupling. |
| PGND (Pins 4,9,16,21) | Power Ground | Source connection of internal N-FET; must tie directly to SW-side ground plane; separate from SGND to avoid noise coupling. |
| SGND (Pin 1) | Signal Ground | Reference for FB, COMP, EN/DLY, RC, DELAY, POR/PG; connects to clean analog ground; isolated from PGND except at single-point star ground. |
| EP | Exposed Thermal Pad | Must be soldered fully to inner-layer GND plane; accounts for >70% of heat dissipation; omission de-rates output current by ~30%. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Power Stage | Monolithic 30 mΩ P-FET + 25 mΩ N-FET eliminates external MOSFETs and gate drivers - reduces BOM count and layout complexity. |
| Ultra-Fast Transient Response | Regulates within ±1% under 0.6A→6A load step (200 µs settling) - critical for FPGA core voltage stability during burst-mode processing. |
| Full Sequencing & Tracking | Three dedicated pins (EN/DLY, RC, DELAY) enable precise turn-on/turn-off order and voltage-ratio matching across multiple rails without external controllers. |
| Micropower Shutdown | 5 µA typical shutdown current - preserves battery life in always-on systems; enables rapid wake-up via EN/DLY capacitor discharge. |
| 100% Duty Cycle Operation | Maintains regulation down to VOUT = VIN − Vdropout; supports low-dropout operation near input rail - useful for post-regulation of 3.3V → 3.0V supplies. |
Applications
| FPGA Core Power | ASIC I/O Supply |

|
Use Scenario: Delivers 1.0V/1.1V to CPU/GPU memory interfaces (DDR4, LPDDR4) in compact server blades with strict thermal limits. IC Role / Device Role / Timing Role: High-density POL converter mounted adjacent to memory controller; uses ePad TSSOP for direct thermal path to heatsink. Use Value: 32.2°C/W θJA allows 6A operation at +85°C ambient; 1 MHz switching enables small 1 µH shielded inductor footprint. |
Use Scenario: Generates stable 3.3V bias for laser driver ICs and transimpedance amplifiers in SFP+/QSFP optical transceivers. IC Role / Device Role / Timing Role: Low-noise, fast-recovery regulator where output ripple <10 mVpp prevents optical signal jitter. Use Value: Ultra-low ESR ceramic output filter (47 µF X5R) + internal compensation yields <50 mV overshoot on 1A→6A step; POR confirms regulation before laser enable. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MP2315GJ-Z (Monolithic Power) | 4A max output, 2.5V–6V input, no RC/DELAY sequencing pins, requires external compensation. | Lacks multi-rail coordination features; suitable only for single-output, non-sequenced systems. | Select when cost sensitivity outweighs sequencing needs and load current ≤4A. |
| TPS546B24RVFT (Texas Instruments) | 6A, 1.5V–16V input, PMBus interface, digital compensation, 3.5mm × 3.5mm QFN. | Supports telemetry and dynamic voltage scaling but adds firmware overhead and layout complexity. | Select when digital monitoring, margining, or adaptive frequency control is required. |

FAQ
What is the maximum output current capability of the MIC22600YTSE-TR?
The MIC22600YTSE-TR delivers up to 6A continuous output current under thermal-limited conditions. This rating assumes proper PCB layout with full-soldered EP pad, ≥2 in² inner-layer GND plane, and ambient temperature ≤+85°C. Peak current limit is 9A (typ), enabling robust overload handling without shutdown.
Does the MIC22600YTSE-TR support adjustable output voltage, and what is the minimum setting?
Yes, the MIC22600YTSE-TR supports adjustable output voltage via an external resistor divider on the FB pin. The internal reference is 0.7V ±1%, allowing outputs as low as 0.7V. For example, a 10 kΩ top resistor and 10 kΩ bottom resistor sets VOUT = 1.4V; lower values (e.g., 5.1 kΩ/10 kΩ) achieve 1.05V.
How does the RC pin function in the MIC22600YTSE-TR, and what capacitor value is recommended?
The RC pin in the MIC22600YTSE-TR sources/sinks a precise 1 µA current to program output voltage slew rate during startup and shutdown. A capacitor from RC to GND sets ramp time: tramp ≈ 1.24V / 1 µA × CRC. Minimum recommended value is 220 pF; typical use cases employ 1 nF–10 nF for controlled soft-start and inter-rail tracking.
What thermal performance can be expected from the MIC22600YTSE-TR in its TSSOP ePad package?
The MIC22600YTSE-TR in 24-pin ePad TSSOP achieves θJA = 32.2°C/W and θJC = 12.9°C/W when the EP pad is fully soldered to a 2-layer PCB with ≥2 in² internal GND plane. At 6A and +85°C ambient, junction temperature remains ≤120°C - within the –40°C to +125°C operating range.
Can the MIC22600YTSE-TR be used in multi-rail sequencing applications, and which pins enable this?
Yes, the MIC22600YTSE-TR is explicitly designed for multi-rail sequencing via three dedicated pins: EN/DLY (enables staggered turn-on), DELAY (controls POR assertion timing), and RC (synchronizes output voltage ramps). These allow "first-up, last-down" sequences and ratio-metric tracking between multiple MIC22600YTSE-TR units without external controllers.
