MIC261201

28V, 12A Hyper Speed Control^®Synchronous

DC/DC Buck Regulator

Features

General Description

• Hyper Speed Control^®Architecture Enables

The MIC261201 is a constant-frequency, synchronous

buck regulator that features a unique adaptive on-time

control architecture. The MIC261201 operates over an

input supply range of 4.5V to 28V and provides a

regulated output of up to 12A of output current. The

output voltage is adjustable down to 0.8V with an

ensured accuracy of ±1%, and the device operates at

a switching frequency of 600 kHz.

- High Delta V Operation (V_IN= 28V and

V_OUT= 0.8V)

- Small Output Capacitance

• 4.5V to 28V Voltage Input

• 12A Output Current Capability, Up to 95%

Efficiency

• Adjustable Output from 0.8V to 5.5V

• ±1% Feedback Accuracy

Microchip’s Hyper Speed Control^®architecture allows

for ultra-fast transient response while reducing the

output capacitance and also makes (High V_IN)/(Low

• Any Capacitor™ Stable: Zero ESR to High ESR

• 600 kHz Switching Frequency

• No External Compensation

V_OUT) operation possible. This adaptive t_ONripple

control architecture combines the advantages of

fixed-frequency operation and fast transient response

in a single device.

• Power Good (PG) Output

• Foldback Current Limit and “Hiccup Mode”

Short-Circuit Protection

The MIC261201 offers a full suite of features to protect

the IC during fault conditions. These include

undervoltage lockout to ensure proper operation under

power-sag conditions, internal soft-start to reduce

inrush current, foldback current limit, “hiccup mode”

short-circuit protection, and thermal shutdown. An

open-drain Power Good (PG) pin is provided.

• Supports Safe Startup into a Pre-Biased Load

• –40°C to +125°C Junction Temperature Range

• 28-Lead 5 mm x 6 mm VQFN Package

Applications

• Distributed Power Systems

• Communications/Networking Infrastructure

• Set-Top Box, Gateways, and Routers
