6261AIRZ

Single-Phase Core Regulator for IMVP-6® Mobile CPUs

Renesas Electronics 

ISL6261A

VSUM

This pin is connected to one terminal of the capacitor in the

current sensing R-C network.

VIN

Power stage input voltage. It is used for input voltage feed

forward to improve the input line transient performance.

VSS

Signal ground. Connect to controller local ground.

VDD

5V control power supply.

NC

Not connected. Ground this pin in the practical layout.

BOOT

Upper gate driver supply voltage. An internal bootstrap diode is

connected to the VCCP pin.

UGATE

The upper-side MOSFET gate signal.

PHASE

The phase node. This pin should connect to the source of

upper MOSFET.

VSSP

The return path of the lower gate driver.

LGATE

The lower-side MOSFET gate signal.

VC24CP

5V power supply for the gate driver.

VID0, VID1, VID2, VID3, VID4, VID5, VID6

VID input with VID0 as the least significant bit (LSB) and VID6

as the most significant bit (MSB).

VR_ON

VR enable pin. A logic high signal on this pin enables the

regulator.

DPRSLPVR

Deeper sleep enable signal. A logic high indicates that the

microprocessor is in Deeper Sleep Mode and also indicates a

slow Vo slew rate with 41A discharging or charging the SOFT

cap.

DPRSTP#

Deeper sleep slow wake up signal. A logic low signal on this

pin indicates that the microprocessor is in Deeper Sleep Mode.

CLK_EN#

Digital output for system PLL clock. Goes active 13 clock

cycles after Vcore is within 20mV of the boot voltage.

3V3

3.3V supply voltage for CLK_EN#.

PGOOD

Power good open-drain output. Needs to be pulled up

externally by a 680 resistor to VCCP or 1.9k to 3.3V.
