Pin Assignments
Pin Denitions
Pin Number
Pin Name
Pin Function Description
1-5
VID0-4
Voltage Identification Code Inputs. Open collector/TTL compatible inputs will
program the output voltage over the ranges specified in Table 1. Internally Pulled-
Up.
6
BYPASS
5V Rail. Bypass this pin with a 0.1
F ceramic capacitor to AGND.
7
AGND
Analog Ground. Return path for low power analog circuitry. This pin should be
connected to a low impedance system ground plane to minimize ground loops.
8
LDRVB
Low Side FET Driver for B. Connect this pin to the gate of an N-channel
MOSFET for synchronous operation. The trace from this pin to the MOSFET gate
should optimally be <0.5".
9
PGNDB
Power Ground B. Return pin for high currents flowing in low-side MOSFET.
Connect directly to low-side MOSFET source.
10
SWB
High side driver source and low side driver drain switching node B. Gate
drive return for high side MOSFET, and negative input for low-side MOSFET
current sense.
11
HDRVB
High Side FET Driver B. Connect this pin to the gate of an N-channel MOSFET.
The trace from this pin to the MOSFET gate should optimally be <0.5".
12
BOOTB
Bootstrap B. Input supply for high-side MOSFET.
13
BOOTA
Bootstrap A. Input supply for high-side MOSFET.
14
HDRVA
High Side FET Driver A. Connect this pin to the gate of an N-channel MOSFET.
The trace from this pin to the MOSFET gate should optimally be <0.5".
15
SWA
High side driver source and low side driver drain switching node A. Gate
drive return for high side MOSFET, and negative input for low-side MOSFET
current sense.
16
PGNDA
Power Ground A. Return pin for high currents flowing in low-side MOSFET.
Connect directly to low-side MOSFET source.
17
LDRVA
Low Side FET Driver for A. Connect this pin to the gate of an N-channel
MOSFET for synchronous operation. The trace from this pin to the MOSFET gate
should optimally be <0.5".
18
VCC
VCC. Internal IC supply. Connect to system 12V supply, and decouple with a 10
resistor and 1
F ceramic capacitor.
19
PWRGD
Power Good Flag. An open collector output that will be logic LOW if the output
voltage is less than 350mV less than the nominal output voltage setpoint. Power
Good is prevented from going low until the output voltage is out of spec for
500sec.
