AME5138 n General Description The AME5138 is a fixed off-time step-up DC/DC converter in a small 5-lead SOT-25 package.
The AME5138 is ideal for LCD panels requiring low current and high efficiency as well as LED applications for cellular phone backlighting, PDAs,and other hand-held devices.
The low 400ns off-time allows the use of tiny external components.
AME5138 is designed to drive up to four white LEDs in series with a constant current from a single Li-lon battery.
To control LED brightness, the LED current can be adjusted by applying a PWM (pulse width modulated) signal with a frequency range of 100Hz to 50KHz to the EN pin.
