MIC22700

1 MHz, 7A Integrated Switch, High Efficiency Synchronous Buck Regulator

Features

General Description

• Input Voltage Range: 2.6V to 5.5V

• Output Voltage Adjustable Down to 0.7V

• Output Load Current Up to 7A

The MIC22700 is a highly efficient, 7A, integrated

switch, synchronous buck (step-down) regulator. The

MIC22700 is optimized for highest efficiency, achieving

more than 95% efficiency while still switching at 1 MHz

over a broad range. The device works with a small 1 μH

inductor and 100 μF output capacitor. The ultra-high

speed control loop keeps the output voltage within

regulation even under extreme transient load swings

commonly found in FPGAs and low-voltage ASICs.

The output voltage can be adjusted down to 0.7V to

address all low voltage power needs. The MIC22700

offers a full range of sequencing and tracking options.

The Enable/Delay pin combined with the Power

Good/POR pin allows multiple outputs to be sequenced

in any way during turn-on and turn-off. The RC (Ramp

Control) pin allows the device to be connected to

another product in the MIC22xxx and/or MIC68xxx

family, to keep the output voltages within a certain ∆V

on start up.

• Full Sequencing and Tracking Ability

• Power-on-Reset/Power Good

• Ultra-Fast Transient Response, Easy RC

Compensation

• 100% Maximum Duty Cycle

• Fully Integrated MOSFET Switches

• Micropower Shutdown

• Thermal Shutdown and Current-Limit Protection

• 24-Pin 4 mm x 4 mm QFN

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

Applications

• High Power Density Point-of-Load Conversion

• Servers and Routers

The MIC22700 is available in a 24-pin 4mm x 4mm

QFN with a junction operating range from –40°C to

+125°C.

• Blu-Ray/DVD Players and Recorders

• Computing Peripherals

• Base Stations

• FPGAs, DSP, and Low Voltage ASIC Power
