TS19378CSRLG Overview

2A Buck (Step-down) WLED Driver

TS19378
Taiwan Semiconductor
2A Buck (Step-down) WLED Driver
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.

I wrote a TLC549 acquisition and display program, but the display was weird.
After powering on, the 8 LED lights used to display the sampling data are all on first, then the highest bit is off, and all the lower bits are off. The program is like this - module amyad(clk,din,clk...
