1W StepupDC-DCWhiteLED Driver Description: Features: Applications:
AP9231 is a PFM Step-up DC/DC driver IC with invariant current, design for LED applications. Thought the external resistance, output current reach 0mA~500mA. A low ripple, high efficiency step-up DC/DC converter can be constructed of AP9231. with only three external components. Also available is a CE (chip enable) function that reduce power consumption.
Low start voltage：0.8V ( at Iout=1mA)
Output Current range：0~ 500mA
Output Current accuracy：±10%
Only inductors, capacitors, Schottky diodes, resistors and so few external components
High Efficiency：82%(Type)
PACKAGE：SOT-23-5，SOT-89-5
Power source for high-power LED
Power source for invariant current
