V_IN

2.7V~4.2V

The AME5136 is a dual Boost DC/DC converter, de-

signed to drive up to 4 white LEDs with a constant cur-

rent and to power an organic LED display with a constant

voltage. According to SEL pin status, the AME5136 can

either regulates output current flowing through series con-

nected LEDs or regulate output voltage applying to OLED.

OVP

A single external resistor is used to set the maximum

LED current. The LED current can be adjusted by apply-

ing a PWM signal to the EN pin. Pulling the EN pin to

GND disables the chip and reduces the supply current to

less than 1uA. Additional features include a low-side NFET

switch that can turn off the LED string with no DC current
