MIC2179BSM規(guī)格書詳情

General Description

The Micrel MIC2179 is a 200kHz synchronous buck (stepdown) switching regulator designed for high-efficiency, battery-powered applications.

The MIC2179 operates from a 4.5V to 16.5V input and features internal power MOSFETs that can supply up to 1.5A output current. It can operate with a maximum duty cycle of 100 for use in low-dropout conditions. It also features a shutdown mode that reduces quiescent current to less than 5μA.

Features

? 4.5V to 16.5V input voltage range

? Dual-mode operation for high efficiency (up to 96)

PWM mode for > 150mA load current

Skip mode for <150mA load current

? 150mΩ internal power MOSFETs at 12V input

? 200kHz preset switching frequency

? Low quiescent current

1.0mA in PWM mode

600μA in skip mode

< 5μA in shutdown mode

? Current-mode control

Simplified loop compensation

Superior line regulation

? 100 duty cycle for low dropout operation

? Current limit

? Thermal shutdown

? Undervoltage lockout

Applications

? High-efficiency, battery-powered supplies

? Buck (step-down) dc-to-dc converters

? Cellular telephones

? Laptop computers

? Hand-held instruments

? Battery Charger
