capacitor, and to EA+ through an external “Droop” resistor.
DSEN# - This pin connects to system logic “STP_CPU#”
and enables Deep Sleep mode of operation. Deep Sleep is
enabled when a logic LOW signal is detected on this pin.
DRSEN - This pin connects to system logic “DPRSLPVR”
and enables Deeper Sleep mode of operation when a logic
HIGH is detected on this pin.
VBAT - Voltage on this pin provides feed-forward battery
information which adjusts the oscillator ramp amplitude.
FSET - A resistor from this pin to ground programs the
switching frequency.
VDD - This pin is used to connect +5V to the IC to supply
all power necessary to operate the chip. The IC starts to
operate when the voltage on this pin exceeds the rising
POR threshold and shuts down when the voltage on this
pin drops below the falling POR threshold.
VDDP - This pin provides a low-esr bypass connection to
the internal gate drivers for the +5V source.
PGOOD - This pin is used as an input and an output and is
tied to the Vccp and Vcc_mch PGOOD signals. During
start-up, this pin is recognized as an input and prevents
further slewing of the output voltage from the “Boot” level
until PGOOD from Vccp and Vcc_mch is enabled High.
After start-up, this pin has an open drain output used to
indicate the status of the CORE output voltage. This pin is
pulled low when the system output is outside of the
regulation limits. PGOOD includes a timer for power-on
delay.
EN - This pin is connected to the system signal VR_ON
and provides the enable/disable function for the PWM
controller.
PWRCH - This pin selects the number of power channels.
A HIGH logic level on this pin enables 2 channel operation,
and a LOW logic signal enables single channel operation.
OCSET - A resistor from this pin to ground sets the
overcurrent protection threshold.
VSEN - This pin is used for remote sensing of the
microprocessor CORE voltage.

ISEN1, ISEN2 - These pins are used as current sense
inputs from the individual converter channel phase nodes.
DACOUT - This pin provides access to the output of the
Digital-to-Analog Converter.
DSV - The voltage on this pin provides the setpoint for
output voltage during Deep Sleep Mode of operation.
DRSV – The voltage on this pin provides the setpoint for
output voltage during Deeper Sleep Mode of operation.
VID0, VID1, VID2, VID3, VID4, VID5 - These pins are used
as inputs to the 6-bit Digital-to-Analog converter (DAC).
VID0 is the least significant bit and VID5 is the most
significant bit.
UG1, UG2 - These pins are the gate-drive outputs to the
high side MOSFETs for channels 1 and 2, respectively.
LG1, LG2 - These pins are the gate-drive outputs to the
low side MOSFETs for channels 1 and 2, respectively.
BOOT1, BOOT2 - These pins are connected to the
bootstrap capacitors, for upper gate-drive, for channels 1
and 2, respectively.
PHASE1, PHASE2 - These pins are connected to the
phase nodes of channels 1 and 2, respectively.
VSSP1, VSSP2 - These pins are connected to the power
ground of channels 1 and 2, respectively.
VSS - This pin provides connection for signal ground.
