SM8130A50D Product details

OVERVIEW

The SM8130 series are a doubler charge pump DC/DC converter with built-in constant current circuit (independent 3ch). Stable output supply can be realized by an input series regulator and an output side charge pump. 1 to 3 lights of white LED connected in parallel can be lighted. Current variation among LED is reduced due to the independent 3ch constant circuit. Current value sent to white LED can be set by supply level of CONT pin. In addition, brightness can also be adjusted by controlling of CONT pin supply.



FEATURES

■ 1 to 3 lights of white LED (connected in parallel) lighted

■ Output current value can be set by CONT pin supply (0.25V: 10mA/pcs, 0.50V: 20mA/pcs)

■ Brightness adjustable by controlling of CONT pin supply

■ Current variation among LED decreased by high precision

■ LED current regulation function for LED protection from excess current (ILIMIT1 to 3 = 30mA ±10%)

■ Input voltage range: 2.7 to 4.6V

■ Output voltage: 5.0V (typ)

■ Quiescent current: 3.5mA (typ)

■ Standby current: 1.0µA (max)

■ Switching frequency: 500kHz (typ)

■ LED current accuracy: 20mA ±3%(VCONT= 0.50V)

■ Package: 10-pin SON



APPLICATIONS

■ Cellular phone

■ Pager

■ Digital still camera

■ Handy terminal

■ PDAs

■ Portable games

■ White LED driving

■ Smart card reader

■ USB port

■ Li-ion battery backup supply

■ PCMCIA local 5V supply

■ Local 3V to 5V conversion
