MIC2182

High-Efficiency Synchronous Buck Controller

General Description

Features

Micrel’s MIC2182 is a synchronous buck (step-down) switch-

ing regulator controller. An all N-channel synchronous archi-

tecture and powerful output drivers allow up to a 20A output

current capabilty. The PWM and skip-mode control scheme

allows efficiency to exceed 95% over a wide range of load

current, making it ideal for battery powered applications, as

well as high current distributed power supplies.

• 4.5V to 32V Input voltage range

• 1.25V to 6V Output voltage range

• 95% efficiency

• 300kHz oscillator frequency

• Current sense blanking

• 5Ω impedance MOSFET Drivers

• Drives N-channel MOSFETs

• 600µA typical quiescent current (skip-mode)

The MIC2182 operates from a 4.5V to 32V input and can

operate with a maximum duty cycle of 86% for use in low-

dropout conditions. It also features a shutdown mode that

reduces quiescent current to 0.1µA.

• Logic controlled micropower shutdown (I < 0.1µA)

• Current-mode control

• Cycle-by-cycle current limiting

• Built-in undervoltage protection

• Adjustable undervoltage lockout

• Easily synchronizable

• Precision 1.245V reference output

• 0.6% total regulation

• 16-pin SOP and SSOP packages

• Frequency foldback overcurrent protection

• Sustained short-circuit protection at any input voltage

• 20A output current capability

The MIC2182 achieves high efficiency over a wide output

current range by automatically switching between PWM and

skip mode. Skip-mode operation enables the converter to

maintain high efficiency at light loads by turning off circuitry

pertaining to PWM operation, reducing the no-load supply

current from 1.6mA to 600µA. The operating mode is inter-

nally selected according to the output load conditions. Skip

mode can be defeated by pulling the PWM pin low which

reduces noise and RF interference.

Applications

The MIC2182 is available in a 16-pin SOP (small-outline

package) and SSOP (shrink small-outline package) with an

operating range from –40°C to +85°C.

• DC power distribution systems

• Notebook and subnotebook computers

• PDAs and mobile communicators

• Wireless modems

• Battery-operated equipment
