Product details
Overview
MIC22200YML-TR from Microchip Technology is a 2A synchronous buck regulator IC with programmable switching frequency (800 kHz–4 MHz), adjustable output down to 0.7V, and full sequencing/tracking capability for multi-rail power systems. It integrates high-side (180 mΩ) and low-side (100 mΩ) MOSFETs, supports ultra-fast transient response, and operates across –40°C to +125°C junction temperature in server and FPGA point-of-load applications.
For engineers reviewing the MIC22200YML-TR datasheet, MIC22200YML-TR pinout, MIC22200YML-TR application, or MIC22200YML-TR equivalent, key selection criteria include its 12-pin 3 mm × 3 mm DFN package, 100% duty cycle capability, Power-On-Reset (POR) output, RC-controlled soft-start, and compatibility with ceramic output capacitors as low as 22 µF.
Technical Context
The MIC22200YML-TR implements voltage-mode PWM control with an internal 1 MHz ramp generator and external RC compensation. Its dual current-source architecture (1 µA on EN/DLY, RC, and DELAY pins) enables precise timing for startup delay, POR assertion, and output voltage slew rate control.
It features integrated P-channel (180 mΩ) and N-channel (100 mΩ) MOSFETs, supports 2.6V–5.5V input, delivers up to 2A load current, and maintains regulation under extreme transient loads typical of FPGAs and low-voltage ASICs via ultra-fast control loop response.
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 2A - Sustains full rated load at 125°C junction temperature with proper thermal layout on PCB. |
| Switching Frequency | Programmable 800 kHz–4 MHz - Adjusted via CF capacitor; higher frequencies reduce inductor size, lower frequencies improve light-load efficiency. |
| Feedback Reference | 0.7V ±2% - Enables precise output setting down to 0.7V using standard resistor divider; stable over –40°C to +125°C. |
| Thermal Protection | Overtemperature shutdown at 160°C - Hysteresis of 25°C prevents oscillation during thermal stress; ensures safe recovery before restart. |
| Quiescent Current | 1.2 mA (PWM mode) - Minimizes standby power loss in always-on subsystems while maintaining fast wake-up capability. |
| Shutdown Current | 3.7 µA - Enables deep-sleep modes in battery-powered or energy-sensitive designs without external disconnect switches. |
Pinout & Package
Package: 12-pin 3 mm × 3 mm DFN (ML) with exposed thermal pad (ePad) requiring full solder connection to PCB ground plane for thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| POR | Open-drain Power-On-Reset output | Signals output regulation status; requires external pull-up (e.g., 47 kΩ) to enable system-level power-good sequencing. |
| RC | Ramp Control input | 1 µA current source sets output voltage slew rate during startup/shutdown; enables tracking with other MIC22X00 devices. |
| CF | Frequency programming input | Capacitor-to-GND sets switching frequency (e.g., 220 pF → 1.4 MHz); determines trade-off between efficiency and component size. |
| SGND | Signal Ground reference | Provides low-noise return path for feedback, compensation, and control circuitry; must be separated from PGND in layout. |
| COMP | Compensation network node | Accepts RC network (e.g., 20 kΩ + 100 pF) to stabilize voltage-mode loop; simplifies design with ceramic output capacitors. |
| FB | Feedback input | Monitors output via resistor divider; internal 0.7V reference enables accurate VOUT adjustment with minimal noise susceptibility. |
| SVIN / PVIN | Signal/Power input supplies | PVIN powers high-side MOSFET; SVIN powers internal logic; both require local 10 µF X5R/X7R ceramic bypassing. |
| SW | Switch node | High-frequency, high-current connection to internal MOSFET drains; demands short, wide PCB traces to minimize EMI and losses. |
| PGND | Power Ground return | Low-impedance return for N-channel MOSFET source and inductor; must connect directly to ePad and input/output capacitors. |
| DELAY | POR delay timing input | 1 µA current source charges external capacitor to set POR assertion delay after VOUT reaches 90% of target. |
| EN/DLY | Enable with built-in delay | 1 µA current source charges external capacitor; device starts when pin voltage exceeds 1.24V threshold. |
| ePad | Exposed thermal pad | Must be soldered to solid GND plane; critical for thermal dissipation (θJA = 40°C/W) and electrical stability. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated MOSFETs | 180 mΩ P-channel and 100 mΩ N-channel switches eliminate external FETs and gate drivers, reducing BOM count and layout area. |
| Full Sequencing Support | EN/DLY, DELAY, and RC pins enable delayed turn-on, windowed sequencing, and ratio-metric tracking across multiple MIC22X00 regulators. |
| Ultra-Fast Transient Response | Control loop maintains output regulation within ±2% during 1 A/µs load steps-critical for FPGA core voltage stability. |
| 100% Duty Cycle Operation | Enables dropout operation down to VIN – VDROP, supporting low-VOUT applications (e.g., 0.7V) even at minimum input (2.6V). |
| Micropower Shutdown | 3.7 µA shutdown current allows integration into always-on systems without compromising battery life or standby power budgets. |

FAQ
What is the maximum output current capability of the MIC22200YML-TR under continuous operation?
The MIC22200YML-TR delivers up to 2A continuous output current across its full operating temperature range (–40°C to +125°C junction), provided the PCB layout includes adequate copper area for the ePad thermal pad and input/output capacitors meet recommended X5R/X7R specifications. Derating applies above 85°C ambient without forced airflow.
How does the RC pin on the MIC22200YML-TR enable voltage tracking between multiple power rails?
The RC pin on the MIC22200YML-TR sources/sinks a precise 1 µA current to control output voltage slew rate. When connected to the RC pin of another MIC22X00 device, it forces synchronized ramp-up/down, ensuring ∆V remains within ±50 mV during startup-meeting DDR memory VDD/VTT tracking requirements without external op-amps or controllers.
Can the MIC22200YML-TR operate with a 2.6V input and still regulate a 0.7V output?
Yes, the MIC22200YML-TR supports 100% duty cycle operation, enabling regulation at minimum input (2.6V) down to 0.7V output. This is achieved by holding the high-side P-channel MOSFET fully on during dropout conditions, maintaining output stability without requiring a higher input voltage margin.
What is the purpose of the DELAY pin on the MIC22200YML-TR, and how is it used in sequencing?
The DELAY pin on the MIC22200YML-TR controls the timing of the POR signal assertion. A capacitor connected to DELAY charges via a 1 µA current source once FB reaches 90% of nominal; POR goes high after the capacitor voltage crosses 1.24V. This enables "first-up, last-down" sequencing when combined with EN/DLY delays across multiple rails.
Does the MIC22200YML-TR require external compensation components, and if so, what are the typical values?
Yes, the MIC22200YML-TR uses external RC compensation on the COMP pin. For a 1.2V output with 1 µH inductor and 47 µF X5R output capacitor, a typical network is 20 kΩ in series with 100 pF. Compensation values scale with inductance and output capacitance per Table 5-2 in the official datasheet DS20006324A.
