36V, 5A/6A Fully Integrated Synchronous

Buck Converters

MAX42405/MAX42406

General Description

Benefits and Features

The MAX42405/MAX42406 ICs are tiny synchronous

buck converters with integrated high-side and low-side

switches. The ICs are designed to deliver up to 6A with

wide input voltages ranging from 4.5V to 36V. Voltage

quality can be monitored by observing the PGOOD

signal. The ICs can operate in dropout by running at a

very high duty cycle, making it ideal for industrial

applications.

•

Multiple Functions for Small Size

• Operating V_INRange of 4.5V to 36V

• 20μA Quiescent Current in Skip Mode

• Synchronous DC-DC Converter with Integrated

Field-Effect Transistors (FETs)

• 400kHz and 1.5MHz Fixed-Frequency Options

• Internal Soft-Start

- 2.5ms for 400kHz

- 3.5ms for 1.5MHz

• Programmable 0.8V to 10V Output

• 3.5mm x 3.75mm, 17-Pin FC2QFN

• Symmetrical Package Offers Superior

Electromagnetic interference (EMI) Performance

The MAX42405/MAX42406 offer programmable voltage

ranges from 0.8V to 10V. Frequency is internally fixed at

400kHz and 1.5MHz, which allows for small external

components and reduced output ripple. The ICs

automatically enter skip mode at light loads with ultra-

low quiescent current of 10μA at no load. This family of

products (including the MAX42408/MAX42410) offers a

pin-to-pin compatible offering from 5A to 10A in a single-

phase configuration, and up to 20A in a dual-phase

configuration. These devices have also been optimized

for dual-phase operation with very high current-sharing

accuracy.

•

Dual Phase Capability

• Can Be Used in Dual-Phase Configuration for

High-Power Design

• Dynamic Current Sharing through Shared VEA

• Low-I_QOperation Capability in Dual Phase

The MAX42405/MAX42406 are available in a small

3.5mm x 3.75mm, 17-pin Flip-Chip Quad Flat No lead

(FC2QFN) package and use very few external

components.

•

Precise Output Voltage Monitoring with PGOOD

Forced–Pulse-Width modulation (PWM) and

Skip-Mode Operation

•

Low Dropout Operation

Overtemperature and Short-Circuit Protection

-40°C to +125°C Operating Temperature Range
