10A EcoSpeed^®Integrated FET

Regulator with 5V LDO and Hiccup Restart

POWER MANAGEMENT

Features

Description

Power system

The SC9301 is a stand-alone synchronous EcoSpeed buck

• ^{Input voltage — 3V to 28V}

regulator with adaptive on-time control architecture. It

• ^{Bias Voltage — 5V LDO or 3V to 5.5V external}

features integrated power MOSFETs, a bootstrap switch,

and a ﬁxed 5V LDO in a 5x5mm package. The device is

highly eﬃcient and uses minimal PCB area. The SC9301

supports using standard capacitor types such as electro-

lytic or specialty polymer, in addition to ceramic, at switch-

ing frequencies up to 1MHz.

• ^{Up to 96% peak eﬃciency}

• ^{Integrated bootstrap switch}

• ^{LDO output current — up to 200mA}

• ^{Reference tolerance — 1% T}_J^{= -40 to +125 °C}

• ^EcoSpeedarchitecture with pseudo-ﬁxed fre-

quency adaptive on-time control

• ^{Pre-bias start-up}

Additional features include programmable cycle-by-cycle

current limit protection, programmable soft-start, under

and over-voltage protection, automatic fault recovery

(hiccup restart), and soft shutdown. The device also pro-

vides separate enable inputs for the PWM controller and

LDO as well as a power good output for the PWM

controller.

Logic input and output control

• ^{Independent enable control for LDO and}

switcher

• ^{Programmable V}_IN^{UVLO threshold}

• ^{Power good output}

• ^{Programmable soft-start time}

All protection: automatic restart on fault

• ^{Over-voltage and under-voltage}

• ^{TC compensated R}_DS(ON)sensed current limit

• ^{Thermal shutdown}

Smart gate drivereduces EMI

Capacitor types: SP, POSCAP, OSCON, and ceramic

Package — 5 x 5(mm), 32-pin MLPQ

Lead-free and halogen-free

RoHS and WEEE compliant
