MAX15158Z

High-Voltage Multiphase Boost Controller

General Description

Beneﬁts and Features

● Wide Operating Range

MAX15158Z 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 MAX15158Z can be dynamically set through the 1V to

2.2V reference input (REFIN) for modular design support.

• 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

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 flex-

ible power sequencing.

● Integration Reduces Design Footprint

• Internal LDO for Bias Supply Generation

• Multiphase Multiple Controller Synchronization and

Interleave

• Output Voltage Sense Level Shifter

MAX15158Z has a dedicated RAMP pin to adjust inter-

nal 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 controller is also pro-

tected against output overvoltage, input undervoltage and

thermal shutdown.

● 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

● 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 tempera-

ture range.

• Discontinuous-Conduction-Mode Operation is

Supported when Using a Diode in Place of the

High-Side MOSFET

Applications

● Communication

● Industrial

● Small 5mm x 5mm TQFNPackage, 0.5mm Pitch

● Automotive

● Multiphase Boost
