DCDC Converter

OptiMOS™ IPOL

IR38163/363/165/365

Single-input Voltage, 15 A & 30 A

Buck Regulators with SVID

FEATURES

DESCRIPTION



Internal LDO allows single 16 V operation

Output Voltage Range: 0.5 V to 0.875*PVin

0.5% accurate Reference Voltage

Intel VR12.5 (Rev 1.5); VR13 (Rev 1.0) and SVID

(Rev 1.7) compliant

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

fully integrated and highly efficient DC/DC regulators with

Intel SVID 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 an Intel SVID

interface.



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



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.

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.



The switching frequency is programmable from 150 kHz to

1.5 MHz.

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

PMBus™ interfaces (IR18163 and IR38363) or SVID and I2C

interfaces (IR38165 and IR38365) 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 mm x 7 mm 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

BASIC APPLICATION

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

5.5V <Vin<16V
