　　general deion

　　the ap1910d is a high-efficiency led driver control

　　ic. it drives leds with constant current and uses

　　fewer components. the ap1910d is an open loop,

　　current mode control ic. it can be programmed to

　　operate in either a constant frequency or constant

　　off-time mode. it includes an 12~500v linear

　　regulator which allows it to work in wide input voltage

　　range without external low voltage power supply.

　　the ap1910d is recommended in buck led drivers

　　applications, led luminance can be easily adjusted

　　by ap1910d&＃39;s 0~ pwm dimming and 0~245mv

　　linear dimming functions

　　the ap1910d is suitable for buck led drivers. the

　　system has excellent stable response because of

　　open loop current mode control. the controller

　　achieves good output current regulation and need no

　　compensation

　　features

　　? buck system efficiency：>90%

　　? open loop peak current controller

　　? internal 12~500v linear regulator

　　? constant current led driver

　　? support linear and pwm dimming interface

　　? requires few external components

　　? 8 lead sop packages

　　? rohs compliant and lead (pb)-free

　　and green (halogen free with commercial

　　standard)

　　? constant off time function for over 50% duty

　　cycle applications
