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. The PWM control circuit is

able to the duty ratio linearly from 0 up to 100%. Since this converter can accommodate an input voltage up to

40V, it is also suitable for the operation via an AC adapter
