6 / 16 page  LTC3407A 6 3407afa PIN FUNCTIONS SW2 (Pin 7): Regulator 2 Switch Node Connection to the Inductor. This pin swings from VIN to GND. POR (Pin 8): Power-On Reset. This common-drain logic output is pulled to GND when the output voltage is not within ±8.5% of regulation and goes high after 216 clock cycles when both channels are within regulation. RUN/SS2 (Pin 9): Regulator 2 Enable and Soft-Start Input. Forcing this pin to VIN enables regulator 2, while forcing it to GND causes regulator 2 to shut down. Connect external BLOCK DIAGRAM RC-Network with desired time-constant to enable soft-start feature. This pin must be driven; do not float. VFB2 (Pin 10): Output Feedback. Receives the feedback voltage from the external resistive divider across the output. Nominal voltage for this pin is 0.6V. Exposed Pad (GND) (Pin 11): Power Ground. Connect to the (–) terminal of COUT, and (–) terminal of CIN. Must be soldered to electrical ground on PCB. 1 2 9 10 8 3 4 11 5 – + – + – + – + EA UVDET OVDET 0.6V 7 0.65V 0.55V – + 0.65V UV OV ITH SWITCHING LOGIC AND BLANKING CIRCUIT S R Q Q RS LATCH BURST ICOMP IRCMP ANTI SHOOT- THRU BURST CLAMP SLOPE COMP EN SLEEP POR COUNTER 0.6V REF OSC OSC REGULATOR 2 (IDENTICAL TO REGULATOR 1) PGOOD1 PGOOD2 SHUTDOWN VIN VIN VIN 6 REGULATOR 1 SW1 GND POR GND SW2 5Ω MODE/SYNC VFB1 RUN/SS1 RUN/SS2 VFB2 |
