Automotive, 2V to 36V, 2.2MHz, 0.6A/1.2A Buck-

Boost Converters with Integrated H-Bridge

Architecture

MAX20039/MAX20040

General Description

Benefits and Features

The MAX20039/MAX20040 ICs are a small, synchronous

buck-boost converter family with integrated high-side and

low-side switches. The MAX20040 is designed to deliver

up to 1.2A with input voltages from 2V to 36V while using

only 52µA quiescent current at no load. The ICs provide

an accurate output voltage of ±2%. Voltage quality can be

monitored by observing the PGOOD signal.

● Meets Stringent Automotive Quality and Reliability

Requirements

• 2V to 36V Operating V Allows Operation in Cold-

Crank Conditions

• Tolerates Input Transients Up to 40V

• EN Pin Compatible from 3.3V to 40V

• 0.6A (max) Output Current (MAX20039)

• 1.2A (max) Output Current (MAX20040)

• -40°C to +125°C Automotive Temperature Range

• AEC-Q100

• Increased Efficiency with Reduced BOM Cost and

Board Space

• Integrated FETs H-Bridge Architecture

• Fixed Output Voltages

The MAX20039/MAX20040 offer a fixed output voltage of

5V and a programmable range of 4.0V to 15V. See the

Ordering Information table for more details. Frequency is

adjustable from 220kHz to 2.2MHz, which allows for small

external components, reduced output ripple, and guar-

antees no AM interference. Skip mode with low quies-

cent current of 52μA is available in the MAX20040B and

MAX20040D versions of the IC. The ICs can operate with

spread-spectrum frequency modulation designed to min-

imize EMI-radiated emissions due to the modulation fre-

quency.

• 20-Pin SWTQFN Package

● Low Quiescent Current Helps Designers Meet

Stringent OEM Current Requirements (B and D

Version only)

• 52μA Quiescent Current when in Standby Mode

• 10μA (max) Quiescent Current in Shutdown Mode

The MAX20039/MAX20040 are available in a small (4mm

x 4mm), 20-pin, side-wettable TQFN package and use

very few external components.

● High Switching Frequency Allows Use of Small

External Components

• 200kHz to 2.2MHz Operating Frequency

• Skip Mode for Efficient Low-Power Operation (B

and D version only)

• Fixed-Frequency PWM Mode

• External Frequency Synchronization

Applications

● Infotainment Systems

● Body Electronics

● Start-Stop Systems

● Point-of-Load (POL) Power Supply

● Power over Coax (PoC)

● Reduced EMI Emissions at the Switching Frequency

• Spread Spectrum Can be Enabled or Disabled
