36V HV Synchronous Boost Controller for

Automotive Infotainment Applications

MAX25201/MAX25202

General Description

Benefits and Features

The MAX25201/MAX25202 are high-performance, cur-

rent-mode PWM controllers with 1.5μA (typ) shutdown

current for wide input voltage range boost converters. The

4.5V to 36V input operating voltage range makes these

devices ideal in automotive applications, such as front-

end preboost or general-purpose boost power supply, for

the first boost stage in high-power LED lighting applica-

tions or to generate audio amplifier voltages. An internal

low-dropout regulator with a 5V output voltage enables the

MAX25201/MAX25202 to operate directly from an auto-

motive battery input. The input operating range can be ex-

tended to as low as 1.8V after startup.

● Meets Stringent OEM Module Power Consumption

and Performance Specifications

• 20µA Quiescent Current in Skip Mode

• ±1.5% FB Voltage Accuracy

• Output Voltage Range: Fixed or Adjustable

Between 3.5V and 60V

● Enables Crank-Ready Designs

• Operates Down to 1.8V After Startup

• Wide Input Supply Range from 4.5V to 36V

● EMI Reduction Features Reduce Interference with

Sensitive Radio Bands Without Sacrificing Wide Input

Voltage Range

The MAX25201/MAX25202's switching frequency oper-

ation (up to 2.2MHz) reduces output ripple, avoids AM

band interference, and allows for the use of smaller exter-

nal components. The switching frequency is resistor ad-

justable from 220kHz to 2.2MHz. Alternatively, the fre-

quency can be synchronized to an external clock. A

spread spectrum option is available to improve system

EMI performance. For high-current applications the dual-

phase MAX25202 is available. The MAX25202 operates

at a fixed 400kHz switching frequency and can be syn-

chronized to an external clock.

• Spread-Spectrum Option

• Frequency-Synchronization Input

• Resistor-Programmable Frequency Between

200kHz and 2.2MHz

● AEC-Q100 Qualified Integration and Thermally

Enhanced Packages Save Board Space and Cost

• Current-Mode Controllers with Forced-Continuous

and Skip Modes

• Thermally Enhanced 16-Pin TQFN-EP Package

● Protection Features Improve System Reliability

• Supply Undervoltage Lockout

The controllers feature a power-OK monitor and under-

voltage lockout. Protection features include cycle-by-cycle

current limit and thermal shutdown. The MAX25201/

MAX25202 operate over the -40°C to +125°C automotive

temperature range.

• Overtemperature and Short-Circuit Protection
