MAX25201/MAX25202

36V HV Synchronous Boost Controller

for Automotive Infotainment Applications

General Description

Beneﬁts and Features

● Meets Stringent OEM Module Power Consumption

The MAX2501/MAX25202 are high-performance, current-

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

rent 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

automotive battery input. The input operating range can

be extended to as low as 1.8V after startup.

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 opera-

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

interference, and allows for the use of smaller external

components. The switching frequency is resistor adjust-

able from 220kHz to 2.2MHz. Alternatively, the frequency

can be synchronized to an external clock. A spread-

spectrum option is available to improve system EMI per-

formance. For high-current applications the dual-phase

MAX25202 is available. The MAX25202 operates at a

fixed 400kHz switching frequency and can be synchro-

nized to an external clock.

• Spread-Spectrum Option

• Frequency-Synchronization Input

• Resistor-Programmable Frequency Between

200kHz and 2.2MHz

● 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
