4.5V to 60V, 1A High-Efficiency, Synchronous,

Inverting Output DC-DC Converters

MAX17577, MAX17578

General Description

Benefits and Features

The Himalaya series of voltage regulator ICs, power mod-

ules, and chargers enable cooler, smaller, and simpler

power-supply solutions. The MAX17577 and MAX17578

are high-efficiency, high-voltage, inverting, Himalaya syn-

chronous DC-DC converters with integrated MOSFETs

and internal compensation. The devices generate output

● Reduces External Components and Total Cost

• Synchronous Operation

• All-Ceramic Capacitors, Compact Layout

• Internal Loop Compensation

• System Ground Referenced I/O Pins (EN/UVLO,

RESET)

voltages (V

) from -0.9V to -36V and can deliver up to

● Flexibility to Support Multiple Rails in a System

• Adjustable Output Voltage Range from -0.9V to

The devices feature peak current-mode control architec-

ture. The MAX17577 operates in continuous conduction

mode (CCM) at all loads; thus, providing a constant fre-

quency operation. The MAX17578 operates in discontinu-

ous conduction mode (DCM) for superior efficiency at light

loads. Low minimum on-time allows higher switching fre-

quencies and small solution sizes.

• Wide 4.5V to (60V - |V

• Up to 1A Output Current

• 400kHz to 2.2MHz Adjustable Frequency with

External Clock Synchronization

● Reduces Power Dissipation

• 90.6% Peak Efficiency

• DCM for Superior Light-Load Efficiency

• 6.2μA Shutdown Current

The devices allow the EN/UVLO, RESET, and RT/SYNC

pins to be driven by signals that are referenced to system

ground, eliminating the need for external-level shifter cir-

cuits. The feedback-voltage regulation accuracy is ±1.3%

over a wide -40°C to +125°C temperature range. The de-

vices are available in a compact 12-pin (3mm x 3mm)

TDFN-EP package. Simulation models are available.

● Operates Reliably in Adverse Industrial Environments

• Hiccup-Mode Overload Protection

• Adjustable Soft-Start

• Monotonic Startup with Prebiased Output Voltage

• Built-In Output-Voltage Monitoring with RESET

• Programmable EN/UVLO Threshold

• Complies with CISPR 32 (EN55032) Class B

Conducted and Radiated Emissions

Applications

● Industrial Control Power Supply

● General-Purpose Point-of-Load

● Gate-Drive Circuits

• Overtemperature Protection

• Wide -40°C to +125°C Ambient Operating

Temperature Range/ -40°C to +150°C Junction

● Motion Control

● Wall-Transformer Regulation

● High-Voltage, Single-Board System
