TheAPW7136A/B/C is a current-mode and fixed frequency
boost converter with an integrated N-FET to drive up to 8
white LEDs in series.
The series conneion allows the LED current to be identical
for uniform brightness. Its low on-resistance of NFET
and feedback voltage reduce power loss and achieve
high efficiency. Fast 1MHz current-mode PWM operation
is available for input and output capacitors and a all
induor while minimizing ripple on the input supply. The
OVP pin monitors the output voltage and ss switching
if exceeds the over-voltage threshold. An internal softstart
circuit eliminates the inrush current during start-up.
