Product details
Overview
MIC2204YML-TR from Microchip Technology is a high-efficiency, 2 MHz synchronous buck DC-DC converter with adjustable output voltage down to 1.0 V, capable of delivering up to 600 mA continuous output current. It integrates high-side P-channel and low-side N-channel MOSFETs, operates from 2.3 V to 5.5 V input, and features ultra-fast transient response (200 kHz GBW) for powering RF circuitry and CPU cores in portable wireless devices.
For engineers reviewing the MIC2204YML-TR datasheet, MIC2204YML-TR pinout, MIC2204YML-TR application, or MIC2204YML-TR equivalent, key selection considerations include its 2 MHz fixed-frequency PWM operation, SYNC_IN/SYNC_OUT daisy-chain capability, internal compensation enabling all-ceramic capacitor design, <340 µA quiescent current in active mode, and thermal/current protection - all within a compact 3 mm × 3 mm VDFN-10L package rated for –40°C to +125°C junction temperature.
Technical Context
The MIC2204YML-TR implements a voltage-mode PWM control architecture with a proprietary internal compensation network, eliminating external compensation components while maintaining stability with a 4.7 µH inductor and 4.7 µF ceramic output capacitor. Its 2 MHz switching frequency is fixed but synchronizable via SYNC_IN (1.8–2.5 MHz range), and multiple units can be daisy-chained using SYNC_OUT to minimize beat frequencies in multi-rail systems.
It employs fully integrated synchronous rectification with on-resistance of 0.72 Ω (high-side) and 0.55 Ω (low-side), supports logic-controlled micropower shutdown (<15 µA), and includes overtemperature shutdown at 160°C with 20°C hysteresis. The BIAS pin supplies an internal 2.3 V bias rail requiring a mandatory 10 nF ceramic bypass capacitor.
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), USB 5 V, and wide-input portable rails without pre-regulation. |
| Output Voltage Range | Adjustable down to 1.0 V - set via external resistor divider on FB pin; internal 1.0 V reference enables precise low-VOUT regulation. |
| Max Output Current | 600 mA - sustained delivery under full load with thermal derating per θJA = 60°C/W (VDFN package). |
| Switching Frequency | 2 MHz (typ.) - fixed PWM operation minimizes EMI in RF-sensitive bands; externally synchronizable from 1.8–2.5 MHz. |
| Quiescent Current | 320 µA (typ.) - enables high light-load efficiency; drops to 6.5 µA in shutdown mode. |
| Feedback Voltage | 1.00 V (±2%) - tight tolerance ensures accurate output voltage setting across temperature and process variation. |
| Thermal Shutdown | 160°C (typ.) - protects against sustained overload or poor PCB thermal design; 20°C hysteresis prevents oscillation. |
Pinout & Package
Package: 10-lead VDFN-10L (3 mm × 3 mm × 0.9 mm body, exposed thermal pad), RoHS-compliant, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (SW) | Switch Node | Internal high-side/low-side MOSFET connection point; drives external inductor; requires low-inductance layout to minimize ringing. |
| 2 (VIN) | Input Supply | Primary power input (2.3–5.5 V); must be bypassed with ≥1 µF X5R/X7R ceramic capacitor close to pin. |
| 3 (SYNC_IN) | External Clock Input | Accepts 1.8–2.5 MHz square wave to synchronize switching; tied low if unused; high level reduces frequency to 1.6 MHz. |
| 4 (SYNC_OUT) | Open-Drain Sync Output | Drives next device's SYNC_IN in master-slave configuration; requires external 10 kΩ pull-up for proper logic levels. |
| 5 (EN) | Enable Control | Active-high logic input; 0.72 V threshold with 20 mV hysteresis; pulls device into <15 µA shutdown state when low. |
| 6 (FB) | Feedback Input | Connects to resistor divider from VOUT; compares against internal 1.0 V reference to regulate output voltage. |
| 7 (BIAS) | Internal Bias Rail | 2.3 V internal LDO output; requires dedicated 10 nF ceramic bypass; not for external loading. |
| 8–10 (GND) | Signal & Power Ground | Three dedicated ground pins - must be connected to low-impedance ground plane; shared return for VIN, SW, and BIAS paths. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62231DRVR | 2.25–6.5 V input; 1.0–6.0 V adjustable output; 600 mA; 3.6 MHz switching; no SYNC_IN. | Lacks synchronization capability; higher fSW increases EMI risk near sensitive receivers. | Preferred where board space is constrained and EMI filtering is feasible; unsuitable for multi-rail sync-critical designs. |
| RT8059ZSP | 2.5–5.5 V input; 0.6–5.0 V output; 600 mA; 2 MHz; SYNC_IN support; 25 µA IQ in shutdown. | Lower shutdown current but lacks SYNC_OUT daisy-chain; different pinout and thermal pad layout. | Valid alternative for single-unit use; requires PCB redesign due to non-pin-compatible footprint and missing SYNC_OUT functionality. |
Compared with TPS62231DRVR and RT8059ZSP, the MIC2204YML-TR uniquely combines 2 MHz synchronization *with* daisy-chain capability (SYNC_IN + SYNC_OUT), internal compensation for minimal BOM count, and guaranteed 600 mA output across –40°C to +125°C - making it optimal for thermally demanding, multi-rail RF subsystems where phase coherence and layout simplicity are critical.

FAQ
What is the maximum output current capability of the MIC2204YML-TR under continuous operation?
The MIC2204YML-TR delivers up to 600 mA of continuous output current when properly heatsinked on a standard 4-layer PCB with adequate copper pour. This rating assumes ambient temperature ≤60°C, input voltage ≥3.0 V, and output voltage ≥1.2 V. Derating applies above 60°C ambient or with reduced input voltage - consult the thermal resistance (θJA = 60°C/W) and electrical characteristics tables in the DS20006454A datasheet for precise limits. The MIC2204YML-TR includes current limit protection that engages at ~1.2 A typical.
Does the MIC2204YML-TR require external compensation components?
No, the MIC2204YML-TR features internal compensation optimized for stability with a 4.7 µH inductor and 4.7 µF X5R/X7R ceramic output capacitor for output voltages ≥1.6 V. For outputs <1.6 V, a 10 µF output capacitor is required. No external RC networks, feed-forward capacitors, or compensation resistors are needed - simplifying layout and reducing BOM count. This internal compensation is validated across –40°C to +125°C and is a defining feature of the MIC2204YML-TR.
Can multiple MIC2204YML-TR devices be synchronized to eliminate beat frequencies in multi-rail systems?
Yes, the MIC2204YML-TR supports master-slave synchronization via its dedicated SYNC_IN and open-drain SYNC_OUT pins. Connecting one device's SYNC_OUT (with 10 kΩ pull-up) to another's SYNC_IN enables deterministic daisy-chain operation - ensuring identical switching frequency and controlled phase relationship. This eliminates audible beat tones and intermodulation products in multi-rail RF power systems, a capability explicitly documented for the MIC2204YML-TR in Section 4.4 and Figure 4-1 of DS20006454A.
What is the recommended input capacitor for the MIC2204YML-TR and why is dielectric type critical?
A minimum 1 µF X5R or X7R ceramic capacitor is required on the VIN pin of the MIC2204YML-TR, placed as close as possible to pins 1 (SW) and 2 (VIN). Y5V and Z5U dielectrics are explicitly prohibited - they lose >70% capacitance over temperature and become resistive at high frequencies, degrading high-frequency noise filtering and risking instability. The MIC2204YML-TR's 2 MHz operation demands low-ESR, stable capacitance; X5R/X7R meet this requirement and are validated in all reference designs.
How does the MIC2204YML-TR achieve >95% efficiency, and at what load conditions is this specified?
The MIC2204YML-TR achieves >95% peak efficiency through fully integrated synchronous rectification (eliminating diode losses), low RDS(ON) MOSFETs (0.72 Ω high-side, 0.55 Ω low-side), and optimized 2 MHz PWM control minimizing switching losses. This efficiency is measured at 3.6 V input, 1.2 V output, and 300 mA load - matching typical cellular phone core rail conditions. Efficiency remains >90% from 100 mA to 500 mA, as confirmed in Figure 2-1 of DS20006454A. The MIC2204YML-TR's efficiency advantage is most pronounced versus non-synchronous or lower-frequency alternatives in portable applications.
