General Description
The APW7136A/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 connection allows the LED current to be iden-
tical for uniform brightness. Its low on-resistance of N-
FET and feedback voltage reduce power loss and achieves
high efficiency. Fast 1MHz current-mode PWM operation
is available for input and output capacitors and a small
inductor while minimizing ripple on the input supply. The
OVP pin monitors the output voltage and stop switching if
exceeds the over-voltage threshold. An internal soft-start
circuit eliminates the inrush current during start-up.
The APW 7136A/B/C also integrates under-voltage
lockout, over-temperature protection and current limit
circuits. The APW7136/A/B/C is available in a SOT-23-6
package.
