MAX25201/MAX25202 36V HV Synchronous Boost Controller for Automotive Infotainment Applications General Description Benefits and Features The MAX2501/MAX25202 are high-performance, current- Meets Stringent OEM Module Power Consumption mode PWM controllers with 1.5A (typ) shutdown current and Performance Specifications for wide input voltage range boost converters. The 4.5V 20A Quiescent Current in Skip Mode to 36V input operating voltage range makes these devices 1.5% FB Voltage Accuracy ideal in automotive applications, such as front-end pre- Output Voltage Range: Fixed or Adjustable boost or general-purpose boost power supply, for the first Between 3.5V and 60V boost stage in high-power LED lighting applications or to Enables Crank-Ready Designs generate audio amplifier voltages. An internal low-dropout Operates Down to 1.8V After Startup regulator with a 5V output voltage enables the MAX25201/ Wide Input Supply Range from 4.5V to 36V MAX25202 to operate directly from an automotive battery EMI Reduction Features Reduce Interference with input. The input operating range can be extended to as Sensitive Radio Bands Without Sacrificing Wide Input low as 1.8V after startup. Voltage Range The MAX25201/MAX25202 s switching frequency oper- Spread-Spectrum Option ation (up to 2.2MHz) reduces output ripple, avoids AM Frequency-Synchronization Input band interference, and allows for the use of smaller exter- Resistor-Programmable Frequency Between nal components. The switching frequency is resistor ad- 200kHz and 2.2MHz justable from 220kHz to 2.2MHz. Alternatively, the fre- Integration and Thermally Enhanced Packages Save quency can be synchronized to an external clock. A Board Space and Cost spread spectrum option is available to improve system Current-Mode Controllers with Forced-Continuous EMI performance. For high-current applications the dual- and Skip Modes phase MAX25202 is available. The MAX25202 operates Thermally Enhanced 16-Pin TQFN-EP Package at a fixed 400kHz switching frequency and can be syn- chronized to an external clock. Protection Features Improve System Reliability Supply Undervoltage Lockout The controllers feature a power-OK monitor and under- Overtemperature and Short-Circuit Protection voltage lockout. Protection features include cycle-by-cycle current limit and thermal shutdown. The MAX25201/ Ordering Information appears at end of datasheet. MAX25202 operate over the -40C to +125C automotive temperature range.
