Description
High Efficiency 1.2MHz 30V Boost LED Driver
ACE715C 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.
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.
ACE715C is available in SOT23-6 package that is PB free.
Features
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
Thermal Shutdown
Over Voltage Protection
Dimming with wide Frequency Range
Available in SOT23-6 Package
Application
Camera Flash White LED
PDA LED back light
Digital still cameras
Typical Application
VER 1.1 1
