MIC2168

1 MHz PWM Synchronous Buck Control IC

Features

General Description

• 3V to 14.5V Input Voltage Range

• Adjustable Output Voltage Down to 0.8V

• Up to 95% Efficiency

The MIC2168 is a high-efficiency, simple-to-use 1 MHz

PWM synchronous buck control IC housed in a small

MSOP-10 package. The MIC2168 allows compact

DC/DC solutions with a minimal external component

count and cost.

• 1 MHz PWM Operation

• Adjustable Current Limit Senses High-Side

N-Channel MOSFET Current

The MIC2168 operates from a 3V to 14.5V input,

without the need of any additional bias voltage. The

output voltage can be precisely regulated down to 0.8V.

The adaptive all N-Channel MOSFET drive scheme

allows efficiencies over 95% across a wide load range.

• No External Current Sense Resistor

• Adaptive Gate Drive Increases Efficiency

• Ultra-Fast Response with Hysteretic Transient

Recovery Mode

The MIC2168 senses current across the high-side

N-Channel MOSFET, eliminating the need for an

expensive and lossy current-sense resistor. Current

limit accuracy is maintained by a positive temperature

coefficient that tracks the increasing R_DS(ON)of the

external MOSFET. Further cost and space are saved

by the internal in-rush-current limiting and digital

soft-start.

• Overvoltage Protection Protects the Load in Fault

Conditions

• Dual-Mode Current Limit Speeds up Recovery

Time

• Hiccup Mode Short-Circuit Protection

• Internal Soft-Start

• Dual Function COMP and EN Pin Allows

Low-Power Shutdown

The MIC2168 is available in a 10-lead MSOP package,

with a wide junction operating range of –40°C to

+125°C.

• Small Size MSOP 10-Lead Package
