ZXLD1321 Datasheet Buck Mode DC-dc Converter

Manufacturer: Zetex (now Diodes Incorporated)

Overview: .DataSheet.co.kr ZXLD1321 Boost mode DC-DC converter for LED driving with 1A output and current.

General Description

The ZXLD1321 is an inductive DC-DC converter, with an internal switch, designed for driving single or multiple LEDs in series up to a total of 1A output current.

Applications cover mercial environments with input voltages ranging from 1.2V to 12V.

The device employs a variable 'on' and 'off' time control scheme with adjustable peak switch current limiting and supports step-up (Boost) mode and self-powering Bootstrap operating modes, offering higher power efficiency and lower system cost than conventional PFM circuitry.

Key Features

  • The feedback control circuitry inside the ZXLD1321 provides excellent load and current regulation, resulting in very stable LED current over the useful life of the battery and over the full operating temperature range. The LED current can be adjusted from 100% down to 10% of the set value by applying a dc voltage to the ADJ pin and down to 1% by applying a PWM signal to the ADJ pin. An onchip LED protection circuit also allows output current to be reduced linearly above a predetermined threshol.
