TS19378CS - 2A Buck (Step-down) WLED Driver

Download the TS19378CS datasheet PDF. This datasheet also covers the TS19378 variant, as both devices belong to the same 2a buck (step-down) wled driver family and are provided as variant models within a single manufacturer datasheet.

General Description

The TS19378 is a high voltage step-down converter designed for driving up to 10 series white LEDs from a 40V system input.

The total LED driving current up to 2A, which is measured through an external current sense resistor.

Its low 200mV feedback voltage reduces power loss and improves efficiency.

Key Features

  • Input Voltage Range 8V~40V Output voltage up to 38V 2A Switch Output Current Duty ratio: 0%~100% PWM control 300kHz Switching Frequency Enable/Disable Functions Soft Start Time Control Current limit and Thermal Shutdown Short Circuit Protections Built-in Internal SW P-CH MOS.

TS19378 2A Buck (Step-down) WLED Driver SOP-8EP Pin Definition: 1. EN/SS 8. COMP 2. GND 7. FB 3. VGATE 6. OVP 4. Vcc 5. SW General Description The TS19378 is a high voltage step-down converter designed for driving up to 10 series white LEDs from a 40V system input. The total LED driving current up to 2A, which is measured through an external current sense resistor. Its low 200mV feedback voltage reduces power loss and improves efficiency. The OVP pin monitors the output voltage and turns off the converter if an over-voltage condition is present due to an open circuit condition. The TS19378 includes current limit, short circuit protection and thermal shutdown protection preventing damage. TS19378 provides high power, high efficiency, and excellent transient characteristics.
