DCDC Converter

OptiMOS™ IPOL

IR38263

Single-input Voltage, 30 A Buck

Regulators with PVID

FEATURES

DESCRIPTION



Internal LDO allows single 16 V operation

Output Voltage Range: 0.5V to 0.875*PVin

0.5% accurate Reference Voltage

Enhanced line/load regulation with Feedforward

Frequency programmable by PMBus™ up to 1.5

MHz

Enable input with Voltage Monitoring Capability

Remote Sense Amplifier with True Differential

Voltage Sensing

This family of OptiMOS™ IPOL devices offers easy-to-use,

fully integrated and highly efficient DC/DC regulators with

PVID and I2C/PMBus™ interface. The on-chip PWM

controller and co-packaged low duty cycle optimized

MOSFETs make these devices a space-efficient solution,

providing accurate power delivery for low output voltage

and high current applications that require a parallel VID

interface.



3 pins (PVID) to program output voltage

These versatile devices offer programmability of switching

frequency, output voltage, and fault/warning thresholds

and fault responses while operating over a wide input

range. Thus, they offer flexibility as well as system level

security in event of fault conditions.

Fast mode I2C and 400 kHz PMBus™ interface for

programming, sequencing and margining output

voltage, and for monitoring input voltage, output

voltage, output current and temperature.

PMBus™ configurable fault thresholds for input

UVLO, output OVP, OCP and thermal shutdown.

Thermally compensated pulse-by-pulse current

limit and Hiccup Mode Over Current Protection

Dedicated output voltage sensing for power good

indication and overvoltage protection which

remains active even when Enable is low.



The switching frequency is programmable from 150 kHz to

1.5 MHz for an optimum solution.

The on-chip sensors and ADC along with the PVID and

PMBus™ interfaces make it easy to monitor and report

input voltage, output voltage, output current and

temperature.



Enhanced Pre-Bias Start up

Integrated MOSFET drivers and Bootstrap diode

Operating junction temp: -40^oC<Tj<125^oC

Thermal Shut Down

Post Package trimmed rising edge dead-time

PMBus™ Programmable Power Good Output

Small Size 5 mmx 7mm PQFN

Pb-Free (RoHS Compliant)

External resistor allows setting up to 16 PMBus™

addresses

APPLICATIONS



Intel® VR13 and VR12.5 based systems



Servers and High End Desktop CPU VRs for non-

core applications



Telecom and storage applications

BASIC APPLICATION

For applications in which Pvin>14V, a 1 ohm resistor is required in series with the boot capacitor.

5.5V <Vin<16V

Optional placeholder for boot resistor.

Default should be 0 ohm
