Pin
No.
Symbol
Description
1
VCC
Power for the internal control circuits. A decoupling capacitor is connected from this pin to ground.
2
VDDBP
Digital Logic power. Connect this pin to VCC with 10 W. Connect 0.1 mF capacitor from this pin to
ground
3
VRDYA
Open drain output. High indicates that the aux output is regulating.
4
EN
Logic input. Logic high enables both outputs and logic low disables both outputs.
5
SDIO
Serial VID data interface.
6
ALERT#
Serial VID ALERT#.
7
SCLK
Serial VID clock.
8
VBOOT
A resistor to GND on this pin sets the Core and Aux Boot−up Voltage
9
ROSC
A resistance from this pin to ground programs the oscillator frequency. This pin supplies a trimmed
output voltage of 2 V.
10
VRMP
Feed−forward input of Vin for the ramp slope compensation. The current fed into this pin is used to
control of the ramp of PWM slope
11
VRHOT#
Thermal logic output for over temperature.
12
VRDY
Open drain output. High indicates that the core output is regulating.
13
VSN
Inverting input to the core differential remote sense amplifier.
14
VSP
Non−inverting input to the core differential remote sense amplifier.
15
DIFF
Output of the core differential remote sense amplifier.
16
TRBST#
Compensation pin for the load transient boost.
17
FB
Error amplifier voltage feedback for core output
18
COMP
Output of the error amplifier and the inverting inputs of the PWM comparators for the core output.
19
IOUT
Total output current monitor for core output. Short it to GND if IMON function is not needed.
20
ILIM
Over current shutdown threshold setting for core output. Resistor to CSCOMP to set threshold.
21
DROOP
Used to program droop function for core output. It’s connected to the resistor divider placed between
CSCOMP and CSREF summing node.
22
CSCOMP
Output of total current sense amplifier for core output.
