AP8802

1A LED Step-Down Converter

General Description

Features

The AP8802 is a step-down DC/DC converter designed to drive

LEDs with a constant current. The device can drive up to thirteen

LEDs, depending on the forward voltage of the LEDs, in series

from a voltage source of 8V to 48V. Series connection of the

LEDs provides identical LED currents resulting in uniform

brightness and eliminating the need for ballast resistors. The

AP8802 switches at frequency up to 500kHz. This allows the

use of small size external components, hence minimizing the

PCB area needed.

•

LED driving current up to 1A

High efficiency up to 92%

Operating input voltage up to 48V

High switching frequency up to 500kHz

PWM/DC input for dimming control

Built-in output open-circuit protection

SOP-8L, SOP-8L-EP (Preview) and DFN3030-10 are

available in “Green” Molding Compound (No Br, Sb)

Lead Free Finish/RoHS Compliant (Note 1)

•

Maximum output current of AP8802 is set via an external resistor

connected between the V_INand SET input pins. Dimming is

achieved by applying either a DC voltage or a PWM signal at the

CTRL input pin. An input voltage of 0.2V or lower at CTRL shuts

down the output at SW and puts the device into a low-current

standby state.

Applications

•

Commercial & industrial lighting

Small LCD panel backlight

Appliances interior lighting

Architecture Detail lighting
