Renesas Electronics 

ISL6218

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.

UG

This pin is the gate drive output to the high side MOSFETs.

LG

This pin is the gate drive output to the low side MOSFETs.

BOOT

This pin is connected to the Bootstrap capacitor for upper gate

drive.

PHASE

This pin is connected to the phase node of the power channel.

+5VDC

+5VDC

VSSP

This pin is the return for the lower gate drive and is connected

to power ground.

VSS

This pin provides connection for signal ground.

Typical Application

Figure 1 shows a Single-Phase Synchronous Buck Converter

circuit used to provide “CORE” voltage regulation for the Intel

Pentium-M mobile processor using IMVP-IV voltage

positioning.

The circuit shows pin connections for the ISL6218 PWM

controller in the 38 Ld TSSOP package.
