MAX17783C

6V to 60V, 2.5A, High Efficiency,

Step-Down DC-DC Converter

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 MAX17783C is a high-ef-

ficiency, high-voltage, Himalaya step-down DC-DC con-

verter with an integrated high-side MOSFET operating

over a wide input-voltage range of 6V to 60V. It can deliver

up to 2.5A current, and generate output voltages from

● Reduces External Components and Total Cost

• Internal Compensation Components

• All-Ceramic Capacitors, Compact Layout

● Reduces Number of DC-DC Regulators to Stock

• Wide 6V to 60V Input-Voltage Range

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

0.9V up to 90% of V . The device features internal com-

• Delivers up to 2.5A Over the Temperature Range

• 400kHz to 2.2MHz Adjustable Frequency with

External Clock Synchronization

pensation.

The MAX17783C device uses peak current-mode control

architecture. The device operates in Low I mode at light

● Reduces Power Dissipation

• 90.4% Peak Efficiency

loads to enable high efficiency. The MAX17783C offers a

low minimum on-time that allows high switching frequen-

cies and smaller solution sizes.

• 3.01μA Shutdown Current

• Low I Mode for Enhanced Light-Load Efficiency

The feedback-voltage regulation accuracy is ±1.6% over

-40°C to +125°C. The MAX17783C is available in a com-

pact 10-pin (3mm x 3mm) TDFN package. Simulation

models are available.

● Operates Reliably in Adverse Industrial Environments

• Hiccup-Mode Overload Protection

• Adjustable and Monotonic Startup with Prebiased

Output Voltage

• Built-In Output-Voltage Monitoring with RESET

• Programmable EN/UVLO Threshold

• Complies with CISPR32(EN55032) Class B

Conducted and Radiated Emissions

• Overtemperature Protection

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

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