MIC24056

12V, 12A High-Efficiency Buck Regulator

SuperSwitcher II

General Description

Features

•

HyperLight Load efficiency – up to 80% at 10mA

Hyper Speed Control architecture enables

− High delta V operation (V_IN= 19V and V_OUT= 0.8V)

− Small output capacitance

Input voltage range: 4.5V to 19V

Output current up to 12A

The Micrel MIC24056 is

constant-frequency,

synchronous DC/DC buck regulator featuring adaptive on-

time control architecture. The MIC24056 operates over a

supply range of 4.5V to 19V. It has an internal linear

regulator which provides a regulated 5V to power the

internal control circuitry. MIC24056 operates at a constant

600kHz switching frequency in continuous-conduction

mode and can be used to provide up to 12A of output

current. The output voltage is adjustable down to 0.8V.

Micrel’s HyperLight Load^®architecture provides the same

high efficiency and ultra-fast transient response as the

Hyper Speed Control architecture under medium to

heavy loads, but also maintains high efficiency under light

load conditions by transitioning to variable frequency,

discontinuous mode operation.

•

Up to 95% efficiency

Adjustable output voltage from 0.8V to 5.5V

±1% FB accuracy

Any Capacitor™ stable − zero-to-high ESR

600kHz switching frequency

Power good (PG) output

Foldback current-limit and “hiccup” mode short-circuit

protection

The MIC24056 offers a full suite of protection features to

ensure protection of the IC during fault conditions. These

include undervoltage lockout to ensure proper operation

under power-sag conditions, thermal shutdown, internal

soft start to reduce the inrush current, foldback current-

limit and “hiccup” mode short-circuit protection. The

MIC24056 includes a power good (PG) output to allow

simple sequencing.

•

Safe start-up into pre-biased loads

–40°C to +125°C junction temperature range

Available in 28-pin 5mm × 6mm QFN package

Applications

•

Servers, work stations

The 12A Hyper Speed Control part, MIC24055, is also

available on Micrel’s web site.

Routers, switches, and telecom equipment

Base stations
