Product details
Overview
MIC2207YML-TR from Microchip Technology is a 2 MHz, 3A synchronous PWM buck regulator with integrated high-side P-channel MOSFET, operating from 2.7V to 5.5V input and delivering adjustable output down to 1.0V with ±1% feedback accuracy. It achieves >94% efficiency at 3A load, supports 100% duty cycle for low-dropout operation, and is optimized for point-of-load conversion in telecom, DDR, and video card power supplies.
For engineers reviewing the MIC2207YML-TR datasheet, MIC2207YML-TR pinout, MIC2207YML-TR application, or MIC2207YML-TR equivalent, key selection criteria include its 2 MHz fixed-frequency PWM control, ultra-fast transient response enabled by proprietary internal compensation (200 kHz closed-loop bandwidth), stable operation with only 1 µH inductor and 4.7 µF output capacitor, and thermal/current protection with –40°C to +125°C junction temperature range.
Technical Context
The MIC2207YML-TR implements a voltage-mode PWM controller with type III internal compensation, enabling stable regulation without external compensation components. Its proprietary architecture delivers >200 kHz closed-loop bandwidth and ultra-fast transient response, critical for dynamic load steps in DDR memory and GPU power rails.
It integrates a low-RDS(ON) P-channel MOSFET (95 mΩ typical) and uses non-synchronous operation requiring an external Schottky freewheeling diode. Control logic includes micropower shutdown (<2 µA), undervoltage lockout (2.55 V typ), and open-drain PGOOD with ±7% output voltage monitoring window.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.7 V to 5.5 V - supports direct connection to 3.3 V or 5 V system rails without pre-regulation. |
| Output Current | Up to 3 A continuous - sufficient for DDR3/DDR4 VDDQ, core logic, or GPU auxiliary rails. |
| Switching Frequency | 2 MHz (±10%) - enables compact filter design with 1 µH inductor and 4.7 µF ceramic output capacitor. |
| Feedback Voltage | 1.000 V ±1% - sets output via resistor divider; enables precise 1.0 V to 5.5 V adjustment with minimal error. |
| Efficiency | >94% at 3 A - achieved via 95 mΩ typical RDS(ON), minimizing conduction loss in high-duty-cycle applications. |
| Duty Cycle Range | 0% to 100% - supports dropout conditions where VIN − VOUT < 500 mV, e.g., 3.3 V → 3.0 V conversion. |
| Junction Temp Range | –40°C to +125°C - qualified for industrial and networking equipment with high ambient temperatures. |
Pinout & Package
Package: 12-pin 3 mm × 3 mm × 0.9 mm DFN-ML (exposed pad). RoHS-compliant, Pb-free, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 12 | SW | Switch node - connects directly to inductor; carries full switching current and high dv/dt; requires short, low-inductance routing. |
| 2, 11 | VIN | Main input supply - dual pins reduce IR drop and improve thermal dissipation; each requires local 10 µF X5R/X7R bypass to PGND. |
| 3, 10 | PGND | Power ground - dedicated return path for high-current PWM loop; must be separated from SGND to avoid noise coupling. |
| 4 | SGND | Signal ground - reference for FB, EN, PGOOD, and internal error amplifier; connects to clean analog ground plane. |
| 5 | BIAS | Bias supply - powers internal reference and control circuitry; requires 0.1 µF ceramic cap to SGND and 10 Ω series resistor from VIN. |
| 6 | FB | Feedback input - senses output via resistor divider; 1 nA input bias enables high-value resistors (e.g., 10 kΩ/10 kΩ) to minimize divider current. |
| 7 | NC | No connect - not bonded; may be left floating or tied to SGND for mechanical stability. |
| 8 | EN | Enable input - active-high logic; threshold 0.85 V typ; hysteresis 50 mV prevents chatter near turn-on point. |
| 9 | PGOOD | Open-drain power-good - asserts low when VOUT deviates >±7%; requires external pull-up to regulated rail (e.g., VOUT). |
| EP | GND | Exposed thermal pad - must be soldered to PCB copper pour for thermal performance (θJA = 60°C/W). |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buck regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MIC2208YML-TR | Externally compensatable version with same pinout; supports wider output capacitor values (≥10 µF) and higher ESR types. | Preferred for designs requiring >4.7 µF output capacitance or using polymer/tantalum caps for hold-up time. | Select MIC2208YML-TR if output capacitor selection is constrained by cost, size, or ESR requirements beyond 4.7 µF X5R. |
| TPS54332DR | 3 A, 28 V input, external MOSFETs; 500 kHz switching; requires external compensation and current sense. | Suitable for higher-input-voltage systems (e.g., 12 V intermediate bus) where MIC2207YML-TR's 5.5 V max VIN is insufficient. | Choose TPS54332DR only when input voltage exceeds 5.5 V or when design flexibility justifies added external components and layout complexity. |
Compared with MIC2207YML-TR, MIC2208YML-TR offers design flexibility for non-standard capacitors but adds no efficiency or transient benefit; TPS54332DR trades integration for input voltage headroom and external control, increasing BOM count and footprint by ≥30%.

FAQ
What is the maximum output current capability of the MIC2207YML-TR?
The MIC2207YML-TR delivers up to 3 A of continuous output current under thermal limits, verified across –40°C to +125°C junction temperature with proper PCB copper area and airflow. Its current limit is 3.5 A minimum in PWM mode, and it maintains regulation up to 3 A with ≤0.5% load regulation error. Derating applies above 85°C ambient unless enhanced thermal design is implemented.
Does the MIC2207YML-TR require an external freewheeling diode?
Yes, the MIC2207YML-TR is a non-synchronous buck regulator and requires an external Schottky diode connected from SW to PGND. The diode must withstand ≥5.5 V reverse voltage and conduct ≥3 A average current; Vishay VSS80LJ2 or ON Semiconductor MBR130LSFT1G are validated alternatives. No diode is needed if using the synchronous variant MIC2207B.
Can the MIC2207YML-TR operate with a 1.0 V output voltage?
Yes, the MIC2207YML-TR supports output voltages down to 1.0 V via the FB pin and an external resistor divider. With VFB = 1.000 V ±1%, a 1.0 V output is achieved using R1 = 0 Ω and R2 = open (direct FB-to-GND connection), or more practically with R1 = 10 kΩ and R2 = 0 Ω. This configuration is explicitly validated in the datasheet's typical application circuits.
What is the purpose of the BIAS pin on the MIC2207YML-TR?
The BIAS pin supplies clean power to the MIC2207YML-TR's internal reference and control circuitry. It must be decoupled with a 0.1 µF ceramic capacitor to SGND and fed through a 10 Ω resistor from VIN to suppress high-frequency switching noise. Omitting this filter degrades reference stability and increases output voltage drift over temperature and line conditions.
How does the PGOOD pin function on the MIC2207YML-TR?
The PGOOD pin on the MIC2207YML-TR is an open-drain output that pulls low when the regulated output voltage deviates by more than ±7% from the target value. It requires an external pull-up resistor (typically 10 kΩ to VOUT) and can drive microcontroller reset inputs or system power sequencing logic. Its response time is <100 µs, and it remains asserted low until VOUT stabilizes within tolerance.
