Overview
HA16116FP/FPJ, HA16121FP/FPJ Switching Regulator for Chopper Type DC/DC Converter Description HA16116FP/FPJ and HA16121FP/FPJ are dual-channel PWM switching regulator controller ICs for use in chopper-type DC/DC converters.
This IC series incorporates totem pole gate drive circuits to allow direct driving of a power MOS FET.
The output logic is preset for booster, step-down, or inverting control in a DC/DC converter.
This logic assumes use of an N-channel power MOS FET for booster control, and a P-channel power MOS FET for step-down or inverting control.
HA16116 includes a built-in logic circuit for step-down control only, and one for use in both step-down and inverting control.
HA16121 has...
