TS19372 Datasheet Buck (step-down) Wled Driver

Manufacturer: Taiwan Semiconductor Company

Overview: Buck (Step-down) WLED Driver with External Switch SOT-25 Pin Definition: 1. SW 2. Ground 3. CT 4. ISENSE 5. VIN ..

General Description

The TS19372 is a continuous mode inductive step-down converter, designed for driving single or multiple series connected LEDs efficiently from a voltage source higher than the LED voltage.

The device operates from an input supply between 6V and 40V and provides 300mA output current to drive external N-channel MOSFET.

TS19372 includes the output switch and a high-side output current sensing circuit, which uses an external resistor to set the nominal average output current.

Key Features

  • Wide Input Voltage Range 6V~40V 300mA Output Current High Efficiency up to 92% Drives up to 3 (1~3W) LEDs @ VIN 12V Drives up to 7 (1~3W) LEDs @ VIN 24V 180kHz Switching Frequency Internal PWM Filter.
