LR8506
1.5MHz 600mA Synchronous
Step-Down Converter
„ INTRODUCTION
The LR8506 is a 1.5MHz constant
frequency, slope compensated current
mode PWM synchronous step-down
converter. High switching frequency
allows the use of small surface mount
inductors and capacitors. The internal
synchronous switch increases efficiency
and eliminates the need for an external
Schottky diode. It is ideal for powering
portable equipment which runs from a
single cell Lithium-Ion battery. 100%
duty cycle provides low dropout
operation, extending battery life in
portable systems. Low output voltages
are easily supported with the 0.6V
feedback reference voltage.
