AME5130 Micropower Step-Up DC/DC Converter n General Description The AME5130 is a fixed off-time step-up DC/DC converter in a small 5-lead SOT-25 package.The AME5130 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. AME5130 can drive up 8 white LEDs from a single LiIon battery DC 2V to 5.5V; can be turned on by putting more than 1V at pin 4(RUN). To control LED brightness, the LED current can be pulsed by applying a PWM (pulse width modulated) signal with a frequency range of 100Hz to 50KHz to the RUN pin. n Typical Application V IN 2.5V-4.2V 5 V IN L 10µH 1 SW ILED COUT 4.
