SC4505 Datasheet High Efficiency Boost Converter

Manufacturer: SEMTECH

Overview: SC4505 High Efficiency Boost Converter for Backlight/Flash LED Driver POWER.

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 LED series operation with optimal current matching.

Key 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 (.
