Additional preview pages of the TS19378 datasheet.

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.

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.
