MAX17524

4.5V to 60V, Dual 3A, High-Eﬃciency,

Synchronous Step-Down DC-DC Converter

General Description

Beneﬁts and Features

● Reduces External Components and Total Cost

• No Schottky - Synchronous Operation

• Internal Compensation Components

The MAX17524 dual 3A, high-efficiency, high-voltage,

synchronous step-down DC-DC converter with integrated

high-side MOSFETs operates over an input-voltage range

of 4.5V to 60V. The device can deliver up to 3A on each

output and generates output voltages from 0.9V up to

• All-Ceramic Capacitors, Compact Layout

● Reduces Number of DC-DC Regulators to Stock

• Wide 4.5V to 60V Input

90% of V . This device features internal compensation.

• Adjustable Output Range from 0.9V up to 90% of

The MAX17524 uses peak current-mode control, and can

be operated in pulse-width modulation (PWM), pulse-fre-

quency modulation (PFM), and discontinuous-conduction

mode (DCM) to enable high efficiency under light-load

conditions.

• Delivers up to 3A on Each Output Over the Tem-

perature Range

• 100kHz to 1.1MHz Adjustable Frequency with

External Clock Synchronization

The feedback-voltage regulation accuracy is accurate to

within ±1.4% over -40°C to +125°C. The device is avail-

able in a 32-pin (5mm x 5mm) Thin QFN (TQFN) pack-

age. Simulation models are available.

• Available in a 32-Pin, 5mm x 5mm TQFN Package

● Independent Input-Voltage Pins for Each Output

● Reduces Power Dissipation

• Peak Eﬃciency of 94.4%

Applications

• PFM and DCM Modes Enable Enhanced Light-

Load Eﬃciency

• Auxiliary Bootstrap Supply (EXTVCC) for Improved

Eﬃciency

● Industrial Control Power Supplies

● General-Purpose Point-of-Load

● Distributed Supply Regulation

● Base Station Power Supplies

● Wall Transformer Regulation

● High-Voltage Single-Board Systems

• 5.2μA Shutdown Current

● Operates Reliably in Adverse Industrial Environments

• Hiccup-Mode Overload Protection

• Independent Adjustable Soft-Start Pin and Pro-

grammable EN/UVLO Pin for Each Output

• Monotonic Startup with Prebiased Output Voltage

• Built-in Independent Output-Voltage Monitoring

with RESET for Each Output

Ordering Information appears at end of data sheet.

• Overtemperature Protection

• High Industrial -40°C to +125°C Ambient Operating

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