The KF8435 is a step down PWM controller with a driving dual output currentto 4.8 A (2.4A+2.4A). ltis ;designed to alow for operating a wide supply voltage range from 9V to 40V. The extemal shutdown function can be controlled by logic level to pull COMP/EN pin down, and then comes into standby mode. The extemal compensation makes feedback control have good line and load regulation with flexible extemal design.

The KF8435 operates in the C C (Constant output Current) mode or CV (Constant output Voltage) mode, and the OCP current value is set by current sensing resisters.

The KF8435 is suitable for the DC/DC switching power applications when requested the current limit function. The devices are available in MSOP-10L packages and require very few external devices for operation.
