Overview
Impala Linear Corporation ILC6375 1 Amp SOT-89 Step Down PWM Switcher Controller General Description The ILC6375 is a high efficiency step-down DC-DC controller 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 softstart circuitry.
Available in a tiny SOT-89 package, the ILC6375 requires an external PNP switching transisitor, an inductor, a shottky diode and capacitors.
Features ! Up to 1 Amp output current ! 85% to 90% efficiency at 0.
5A to1A (VIN = 7V, VOUT = 5V) ! 85% efficiency at 10mA (VIN = 7V, VOUT = 5V) ! 100% Duty Cycle for ultra l...
