Datasheet Summary
SC4505 High Efficiency Boost Converter for Backlight/Flash LED Driver
POWER MANAGEMENT Description
The SC4505 is a high-frequency PWM current-mode stepup switching regulator with an integrated 2A power transistor. Its high switching frequency (1MHz) allows the use of tiny surface-mount external passive ponents. The internal switch is rated at 36V which makes the converter ideal for multiple LED series operation with optimal current matching. Two programmable independent current source structure allows dual panel LED backlight and flash operation. .. The operating frequency of the SC4505 is set at 1MHz. The selected operating frequency gives the SC4505 design flexibility...
