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
