MAX15158/MAX15158A

High-Voltage Multiphase Boost Controller

General Description

Beneﬁts and Features

● Wide Operating Range

MAX15158/MAX15158A is a high-voltage multiphase

boost controller designed to support up to two MOSFET

drivers and four external MOSFETs in single-phase

or dual-phase boost/inverting-buck-boost configurations.

Two devices can be stacked up for quad-phase operation.

The output voltage of MAX15158 can be dynamically

set through the 1V to 2.2V reference input (REFIN) for

modular design support. For MAX15158A the REFIN pin

is removed, and the internal 2.0V reference voltage is

selected by default.

• 8V to 76V Input Voltage Range for Booost

Conﬁguration and -8V to -76V Input Voltage Range

for Inverting-Buck-Boost Conﬁguration

• 3.3V to 60V Output Voltage Range on the Top of

Input Voltage

• 120kHz to 1MHz Switching Frequency Range

• -40°C to +125°C Temperature Range

• Single/Dual/Quad-Phase Operation

• Active Phase Current Balance Control

● Integration Reduces Design Footprint

• Internal LDO for Bias Supply Generation

• Multiphase Multiple Controller Synchronization and

Interleave

The switching frequency is controlled either through

an external resistor setting the internal oscillator or by

synchronizing the regulator to an external clock. The

device is designed to support 120kHz to 1MHz switching

frequencies. The controller has a dedicated enable/input

undervoltage-lockout (EN/UVLO) pin to configure for flexible

power sequencing.

• Output Voltage Sense Level Shifter

● Robust Fault Protection Improves Quality and

Reliability

• Adjustable Input Undervoltage Lockout

• Adjustable Cycle-by-Cycle Peak Current Limit

and Fast Overcurrent Protection

• Selectable Feedback Overvoltage Protection

• Thermal Shutdown

MAX15158/MAX15158A has a dedicated RAMP pin to

adjust internal slope compensation. The device features

adjustable overcurrent protection. The device incorporates

current sense amplifiers to accurately measure the current

of each phase across external sense resistors to

implement accurate phase current sharing. The control-

ler is also protected against output overvoltage, input

undervoltage and thermal shutdown.

● Flexible and Simple System Design

• Adjustable Slope Compensation

• Low-Side MOSFET Gate Monitoring for Accurate

Current Sensing

The device is available in 5mm x 5mm, 32-pin TQFN

package and supports -40°C to 125°C junction temperature

range.

• Discontinuous-Conduction-Mode Operation is

Supported when Using a Diode in Place of the

High-Side MOSFET

Applications

● Industrial

● Small 5mm x 5mm TQFN package, 0.5mm pitch

Ordering Information appears at end of data sheet.

● Automotive

● Multiphase Boost
