AME5130
Micropower Step-Up DC/DC Converter
The AME5130 is a fixed off-time step-up DC/DC con-
verter in a small 5-lead SOT-25 package.The AME5130
is ideal for LCD panels requiring low current and high effi-
ciency as well as LED applications for cellular phone back-
lighting, PDAS,and other hand-held devices. The low
400ns off-time allows the use of tiny external compo-
nents.
AME5130 can drive up 8 white LEDs from a single Li-
Ion 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.
