ISL70002SEH - Intersil

ISL70002SEH Radiation Hardened and SEE Hardened 12A Synchronous Buck Regulator

R64.A R64.C PIN NUMBER PIN NUMBER PIN NAME DESCRIPTION 1 FB This pin is the voltage feedback input to the internal error amplifier. Connect a resistor from FB to VOUT and from FB to AGND to adjust the output voltage in accordance with Equation 1: VOUT = VREF  1 + RT  RB (EQ. 1) Where: VOUT = Output voltage VREF = Reference voltage (0.6V typica.
