6A Digital PoL DC-DC Converter with

InTune Automatic Compensation

General Description

Beneﬁts and Features

● InTune Automatic Compensation Simplifies and

The MAX15303 is a full-featured, flexible, efficient, 6A

digital point-of-load (PoL) controller with integrat-

ed switching MOSFETs. It contains advanced power-

management and telemetry features. Unlike PID-based

digital power regulators, the device uses Maxim’s

patented InTune™ automatically compensated, state-

space control algorithm. The InTune control law is valid for

both the small- and large-signal response and accounts

for duty-cycle saturation effects. These capabilities

result in fast loop transient response and reduce the

number of output capacitors compared to competing digital

controllers.

Speeds Design

• Ensures Stability While Optimizing Transient

Performance

• State-Space Compensation Results in Fast

Transient Response with Reduced Output

Capacitance

● Out-of-the-Box Operation Enables Fast Prototyping

• Supports Pin-Strappable Configuration: Output

Voltage, SMBus Address, Switching Frequency,

Current Limit

● Easy to Use PMBus Interface for Configuration,

Control, and Monitoring

To help maximize system efficiency and reduce over-

all parts count, the device uses Maxim’s BabyBuck

regulator. The BabyBuck eliminates the need for an

external bias supply. The BabyBuck can be configured in

two different modes to maximize system flexibility.

• Flexible Sequencing and Fault Management

• Supports Voltage Positioning

• Configurable Soft-Start and Soft-Stop Time

• 300kHz to 1000kHz Fixed-Frequency Operation

The device is designed to minimize the end customer’s

design time. Automatic compensation eliminates the

need for external compensation circuitry and allows

changes to the output inductor and capacitor, without the

need to manually redesign the compensation circuitry.

An on-board PMBus™-compliant serial bus interface

enables communication with a supervisory controller for

monitoring and fault management. A full suite of power-

management features eliminates the need for compli-

cated and expensive sequencing and monitoring ICs.

Basic DC-DC conversion operation can be set up through

pin strapping and does not require user-configuration

firmware. This allows for rapid development of the power-

supply subsystem before board-level systems engineer-

ing is completed. Maxim provides support hardware and

software for configuring the device.

● Integration Yields Small Solution Size

• Integrated High- and Low-Side MOSFETs

• Efficient On-Chip BabyBuck Regulator for Self-

Bias Output

• Startup into a Prebiased Output

● Performance Optimized for Communication and

Computing Systems

• Differential Remote Voltage Sensing Enables

±1.25% V

Accuracy over Temperature

OUT

(-40°C to +85°C)

• 4.5V to 14V Wide Input Range

• Output Voltage Range from 0.5V to 5.25V

• External Synchronization

Applications

● Servers

● Storage Systems

● Routers/Switches

● Base-Station Equipment

● Power Modules

The MAX15303 is available in a 40-pin, 6mm x 6mm TQFN

package with an exposed pad and operates over the -40°C

to +85°C temperature range.
