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
