A7630

DC-DC CONVERTER BOOST (STEP-UP)

1.2MHz, 28V STEP-UP LED DRIVER

AiT Semiconductor Inc.

DESCRIPTION

FEATURES

A7630 is a step-up converter designed for driving

up to 7 series white LED's from a single cell Lithium

Ion battery. Its low 250mV feedback voltage

reduces power loss and improves efficiency.



2.5V to 5.5V Input Voltage

Drivers up to 8 Series WLEDs

Low 250mV Feedback Voltage

1.2MHz Fixed Switching Frequency

Internal 1.6A Switch Current Limit

Internal Compensation

Optimized operation frequency can meet the

requirement of small LC filters value and low

operation current with high efficiency. Internal soft

start function can reduce the inrush current. Tiny

package type provides the best solution for PCB

space saving and total BOM cost.

Thermal Shutdown

Over Voltage Protection

Dimming with wide Frequency Range

Available in SOT-26 Package

APPLICATION

The A7630 is available in SOT-26 package.



Camera Flash White LED

PDA LED back light

Digital still cameras
