The ILC6375 is a high efficiency step-down DC-DC con-
troller using a PWM control scheme. The typical efficiency
can be as high as 85% to 90% at 10mA to 1 Amp load.
The ILC6375 drives an external switching transistor to
deliver up to 1 Amp of output current. The internal oscillator
operates at a fixed 100kHz frequency. Meanwhile, the
device is capable of 100% duty cycle thus allowing true low
drop-out operation to maximize battery life in portable
applications. Output voltage is trimmed to ±2.5% accuracy.
The device includes internal phase compensation and soft-
start circuitry. Available in a tiny SOT-89 package, the
ILC6375 requires an external PNP switching transisitor, an
inductor, a shottky diode and capacitors.
