Product details
Overview
MIC2204YMM-TR from Microchip Technology is a high-efficiency, 2 MHz synchronous buck DC-DC converter with integrated MOSFETs, operating from 2.3V to 5.5V input and delivering up to 600 mA at output voltages down to 1.0 V. It features ultra-fast transient response (200 kHz GBW), internal compensation, and full ceramic capacitor support-designed for RF power supplies and Li-ion–powered portable electronics.
For engineers reviewing the MIC2204YMM-TR datasheet, MIC2204YMM-TR pinout, MIC2204YMM-TR application, or MIC2204YMM-TR equivalent, key selection criteria include its 2 MHz fixed-frequency PWM operation, SYNC_IN/SYNC_OUT daisy-chain capability, <340 µA quiescent current in active mode, and thermal/current protection for robust embedded power delivery.
Technical Context
The MIC2204YMM-TR implements voltage-mode PWM control with a proprietary internal compensation architecture enabling stable operation using only a 4.7 µH inductor and 4.7 µF ceramic output capacitor. Its 200 kHz gain-bandwidth ensures sub-microsecond load transient recovery-critical for CPU core and RF circuitry powering in cellular handsets.
It integrates complementary P-channel high-side and N-channel low-side MOSFETs (RDS(ON) = 0.72 Ω / 0.55 Ω), supports external clock synchronization from 1.8 MHz to 2.5 MHz via SYNC_IN, and provides open-drain SYNC_OUT for master-slave daisy-chaining of multiple converters without phase skew.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.3 V to 5.5 V - supports single-cell Li-ion (3.0–4.2 V) and USB-powered systems without pre-regulation. |
| Output Current | 600 mA max - sufficient for baseband processors, WLAN transceivers, and sensor subsystems. |
| Switching Frequency | 2 MHz (typ.) - enables compact magnetics and avoids AM/FM/ISM bands; adjustable ±20% via SYNC_IN. |
| Feedback Reference | 1.00 V (±2%) - sets output voltage via resistor divider; enables precise 1.0 V–5.0 V adjustment. |
| Quiescent Current | 320 µA (typ.) - minimizes standby drain in always-on subsystems; drops to 6.5 µA in shutdown. |
| Thermal Protection | 160°C shutdown with 20°C hysteresis - prevents latch-up during sustained overload or poor PCB thermal design. |
| Efficiency | >95% at mid-load - reduces heat generation and extends battery runtime in portable devices. |
Pinout & Package
Package: 10-pin MSOP (3.0 mm × 4.9 mm × 1.0 mm, JEDEC MO-187AA), RoHS-compliant, –40°C to +125°C junction temperature rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 SW | Switch Node | Drives external inductor; connects internally to both high-side P-MOSFET drain and low-side N-MOSFET source. |
| 2 VIN | Main Input Supply | Accepts 2.3–5.5 V; requires ≥1 µF X5R/X7R ceramic bypass capacitor close to pin. |

| 4 SYNC_OUT | Open-Drain Sync Output | Drives next MIC2204's SYNC_IN in daisy-chain; requires external 10 kΩ pull-up to VIN. |
| 5 EN | Enable Control | Active-high logic input; 0.72 V threshold with 20 mV hysteresis; enables micropower shutdown (<15 µA). |
| 6 FB | Feedback Input | Connects to resistor divider; compares against 1.00 V internal reference to regulate output voltage. |
| 7 BIAS | Internal Bias Supply | 2.3 V regulated output; must be decoupled with 10 nF ceramic capacitor-no external loading permitted. |
| 8–10 GND | Power Ground | Three dedicated ground pins minimize ground bounce and improve EMI performance; connect to solid ground plane. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62231DRYT | 2.25 V–5.5 V input; 600 mA; 3.6 MHz switching; no SYNC_IN; smaller 2 mm × 2 mm DSBGA package. | Lacks daisy-chain sync and has higher quiescent current (12 µA shutdown vs. 6.5 µA); better suited for space-constrained but less noise-sensitive apps. | Select when board area is critical and RF coexistence is not required. |
| RT8059GJ6F | 2.5 V–5.5 V input; 600 mA; 2 MHz; SYNC_IN supported; 1.0 V feedback reference; 10-pin WDFN (3 mm × 3 mm). | Same functional scope but different thermal resistance (θJA = 65°C/W vs. MSOP's 115°C/W); requires revised thermal pad layout. | Choose for thermally demanding environments where VDFN thermal performance is preferred over MSOP form factor. |
Compared with TPS62231DRYT and RT8059GJ6F, the MIC2204YMM-TR uniquely combines 2 MHz daisy-chain synchronization, 200 kHz GBW for fastest transient response, and MSOP packaging with proven manufacturability in high-volume portable assembly-making it optimal for RF-integrated handheld designs requiring deterministic timing and minimal EMI coupling.

FAQ
What is the recommended input capacitor for MIC2204YMM-TR?
A minimum 1 µF X5R or X7R ceramic capacitor is required on the VIN pin, placed as close as possible to pins 2 (VIN) and 8–10 (GND). Y5V dielectrics are explicitly discouraged due to severe capacitance loss over temperature and high-frequency resistive behavior, which degrades high-frequency noise filtering and can cause instability in the MIC2204YMM-TR.
Does MIC2204YMM-TR support adjustable output voltage, and how is it set?
Yes, MIC2204YMM-TR supports adjustable output voltage from 1.0 V to 5.0 V using an external resistor divider on the FB pin. The internal 1.00 V reference is compared against the divider's midpoint; output voltage is calculated as VOUT = 1.0 V × (1 + R1/R2). A 10 kΩ total divider resistance is recommended to minimize noise susceptibility and ensure stability.
Can MIC2204YMM-TR operate without an external inductor?
No, MIC2204YMM-TR requires an external 4.7 µH shielded power inductor rated for ≥750 mA saturation current. The device relies on this inductor for energy storage and ripple current handling; omitting it will cause immediate failure. Inductor DCR must be ≤215 mΩ to maintain >90% efficiency at full load, per Microchip's validated designs.
What is the function of the BIAS pin on MIC2204YMM-TR, and can it power external circuitry?
The BIAS pin on MIC2204YMM-TR provides a dedicated 2.3 V internal bias supply for the controller's analog circuitry and must be decoupled with a 10 nF ceramic capacitor to GND. It is not intended to source external current-loading the BIAS pin will degrade regulation accuracy and may cause oscillation. External circuits must use separate LDOs or charge pumps.
How does the SYNCLOCK feature work in MIC2204YMM-TR, and what is its benefit?
The SYNCLOCK feature in MIC2204YMM-TR uses the open-drain SYNC_OUT pin to drive the SYNC_IN pin of another MIC2204YMM-TR, forcing identical switching frequencies and deterministic phase alignment. This eliminates beat frequencies between multiple converters-reducing conducted EMI and preventing intermodulation distortion in RF sections powered by separate MIC2204YMM-TR units.
