FB3 is a Dual Mode input that also selects the 3.3V fixed output voltage setting when tied to GND. Connect FB3 to a resistor divider for adjustable-output mode. FB3 3 12V/120mA Linear Regulator Output. Input supply comes from VDD. Bypass 12OUT to GND with 1µF minimum. 12OUT (MAX1630/ 32/33/35) Current-Sense Input. Also serves as the feedback input in fixed-output mode. CSL3 2 FUNCTION NAME PIN Logic-Control Input for secondary feedback. Selects the PWM that uses a transformer and secondary feedback signal (SECFB): STEER = GND: 3.3V SMPS uses transformer STEER = VL: 5V SMPS uses transformer STEER (MAX1631/ MAX1634) Current-Sense Input for the 3.3V SMPS. Current-limit level is 100mV referred to CSL3. CSH3 1 4 |
