MAX17632

4.5V to 36V, 2A, 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 MAX17632 family of parts (MAX17632A, MAX17632B

and MAX17632C) is a high-efficiency, high-voltage, syn-

chronous step-down DC-DC converter with integrated

MOSFETs operating over an input-voltage range of 4.5V

to 36V. It can deliver up to 2A current. The MAX17632A

and MAX17632B are fixed 3.3V and fixed 5V output parts,

respectively. The MAX17632C is an adjustable output

• All-Ceramic Capacitors, Compact Layout

● Reduces Number of DC-DC Regulators to Stock

• Wide 4.5V to 36V Input

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

• Delivers Up to 2A Over Temperature Range

• 400kHz to 2.2MHz Adjustable Frequency with

External Clock Synchronization

voltage (0.9V to 90% of V ) part. Built-in compensation

across the output-voltage range eliminates the need for

external compensation components.

• Available in a 16-Pin, 3mm x 3mm TQFN Package

The MAX17632 features peak-current-mode control archi-

tecture. The device can be operated in the forced pulse-

width modulation (PWM), or pulse-frequency modulation

(PFM), or discontinuous-conduction mode (DCM) to enable

high efficiency under full-load and light-load conditions. The

MAX17632 offers a low minimum on time that allows high

switching frequencies and a smaller solution size.

● Reduces Power Dissipation

• Peak Efﬁciency > 90%

• PFM and DCM Modes Enable Enhanced Light-

Load Efﬁciency

• Auxiliary Bootstrap Supply (EXTVCC) for Improved

Efﬁciency

• 2.8μA Shutdown Current

The feedback-voltage regulation accuracy over -40°C to

+125°C for the MAX17632A/MAX17632B/MAX17632C is

±1.2%.The device is available in a 16-pin (3mm x 3mm)

TQFN package. Simulation models are available.

● Operates Reliably in Adverse Industrial Environments

• Hiccup-Mode Overload Protection

• Adjustable and Monotonic Startup with Prebiased

Output Voltage

Applications

• Built-in Output-Voltage Monitoring with RESET

• Programmable EN/UVLO Threshold

• Overtemperature Protection

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

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

Temperature Range

● Industrial Control Power Supplies

● General-Purpose Point-of-Load

● Distributed Supply Regulation

● Base Station Power Supplies

● Wall Transformer Regulation

● High Voltage Single-Board Systems
