SC402B

10A EcoSpeed^®Integrated FET

Regulator with Programmable LDO

POWER MANAGEMENT

Features

Description



Power System

The SC402B is a stand-alone synchronous EcoSpeed buck

• Input voltage — 3V to 28V

• Bias voltage — 3V to 5.5V LDO or external

• Up to 96% peak eﬃciency

• Integrated bootstrap switch

• Programmable LDO output — 200mA

• Reference tolerance — 1% T_J= -40 to +125 °C

• Programmable soft start time

Logic Input/Output Control

power supply which incorporates Semtech’s advanced

patented adaptive on-time control architecture. This pro-

vides excellent light-load efficiency and fast transient

response. It features integrated power MOSFETs, a boot-

strap switch, and a programmable LDO in a 5x5mm

package. The device is highly eﬃcient and uses minimal

PCB area. The SC402B has the same package and pin con-

ﬁguration as the entire SC40x series for compatibility.



• Independent EN controls for LDO and switcher

• Programmable V_INUVLO threshold

• Power good output

The SC402B supports using standard capacitor types such

as electrolytic or specialty polymer, in addition to ceramic,

at switching frequencies up to 1MHz. The programmable

frequency, synchronous operation, and selectable power-

save provide high eﬃciency operation over a wide load

range.

• Selectable PSAVE or FCM mode

Protection

• Over-voltage and under-voltage

• TC compensated R_DS(ON)sensed current limit

• Thermal Shutdown



Output Capacitor Types

Additional features include a programmable soft-start,

programmable cycle-by-cycle over-current limit protec-

tion, under-voltage and over-voltage protection, soft

shutdown, and selectable power-save operation. The

device also provides separate enable inputs for the PWM

controller and LDO as well as a power good output for the

PWM controller.

• High ESR — SP, POSCAP, OSCON

• Ceramic capacitors

Package

• Lead-free package — 5x5mm, 32-Pin MLPQ

• RoHS/WEEE compliant and Halogen free

Applications

The wide input and programmable frequency make the

device extremely ﬂexible and easy to use in a broad range

of applications.
