SC4505

High Efficiency Boost Converter

SC4505 Features

* ‹ Two independent current sources for dual LED strands with optimal current/light matching. Backlight up to 75mA, Flash up to 125mA ‹ Wide input range from 2.6V to 12V ‹ Adaptive output voltage up to 28V with OVP protection against open circuit conditions ‹ Low shutdown current (

SC4505 General 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 components. The internal switch is rated at 36V which makes the converter ideal for multiple LE.
