Low Cost Micro Power Boost DC/DC Converter

The AME5170A is a fixed off-time Step-up DC/DC con- verter in a small SOT-25 package. The AME5170A is ideal for LCD panels requiring low current and high effi- ciency as well as LED application for cellular phone back- lighting, PDAs, and other hand-held devices. The low 400ns off time allows the use of tiny external compo- nents. AME5170A 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 modu- lated) signal with a frequency range of 100Hz to 50KHz to the EN pin. By AME, Inc.
