Description

The ST1S10 is a high efficiency step-down PWM

current mode switching regulator capable of

providing up to 3 A of output current. The device

operates with an input supply range from 2.5 V to

18 V and provides an adjustable output voltage

■ Stand-by supply current: max 6 µA over

temperature range

■ Operative junction temp: from -25°C to 125°C

from 0.8 V (V ) to 0.85*V

IN_SW OUT

Applications

*(1+R1/R2)]. It operates either at a 900 kHz

fixed frequency or can be synchronized to an

external clock (from 400 kHz to 1.2 MHz). The

high switching frequency allows the use of tiny

SMD external components, while the integrated

synchronous rectifier eliminates the need for a

Schottky diode. The ST1S10 provides excellent

transient response, and is fully protected against

thermal overheating, switching over-current and

output short circuit.

■ Consumer

– STB, DVD, DVD recorders, TV, VCR, car

audio, LCD monitors

■ Networking

– XDSL, modems, DC-DC modules

■ Computer

– Optical storage, HD drivers, printers,

audio/graphic cards

The ST1S10 is the ideal choice for point-of-load

regulators or LDO pre-regulation.

■ Industrial and security

– Battery chargers, DC-DC converters, PLD,

PLA, FPGA, LED drivers
