APE1612 - 1.9A FIXED FREQUENCY WHITE LED DRIVER

Datasheet Summary

Description

The APE1612 is a step-up converter designed for driving up to 8 series white LEDs for backlighting application.

The APE1612 uses current mode, 1.2MHz fixed frequency architecture to regulate the LED current, which is set through an external current sense resistor.

Features

  • 2.5V to 5.5 V Operating Input Voltage Rang Drives up to 8 Series White LEDs 1.2MHz Fixed Switching Frequency Wide Range for PWM Dimming (200Hz to 200KHz) Internal 1.9A Switching Current Limit Over Voltage Protection (OVP) Internal Soft-start Function Current Limit and Thermal Shutdown Protection Under Voltage Lockout Available in the TSOT-26 Packages.

APE1612 1.9A FIXED FREQUENCY WHITE LED DRIVER FEATURES 2.5V to 5.5 V Operating Input Voltage Rang Drives up to 8 Series White LEDs 1.2MHz Fixed Switching Frequency Wide Range for PWM Dimming (200Hz to 200KHz) Internal 1.9A Switching Current Limit Over Voltage Protection (OVP) Internal Soft-start Function Current Limit and Thermal Shutdown Protection Under Voltage Lockout Available in the TSOT-26 Packages DESCRIPTION The APE1612 is a step-up converter designed for driving up to 8 series white LEDs for backlighting application. The APE1612 uses current mode, 1.2MHz fixed frequency architecture to regulate the LED current, which is set through an external current sense resistor. Its low 300mV feedback voltage reduces power loss and improves efficiency.
