Impala Linear Corporation ILC6377 0.5A, 300kHz, SO-8 PWM/PFM Step Down Converter with Shutdown General Description The ILC6377 is a 95% efficient, 300kHz step-down DC-DC converter in an SO-8 package; capable of delivering 500mA output current. The device is also capable of driving an external FET for higher output current applications. The ILC6377 uses a unique p-channel architecture with built-in charge pump to maintain low on-resistance, even at low input voltages. At high or normal currents the ILC6377 operates in PWM mode with 300kHz operating frequency. When the load current drops and the device hits approximately 17% duty cycle, it automatically switches over to PFM or pulse skipping mode. PFM (pulse frequency modulation) mode of operation extends efficiency at light loads.
