The MAX25201/MAX25202 are high-performance, current-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 applications 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.

The MAX25201/MAX25202’s switching frequency operation (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 adjustable 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 performance. For high-current applications the dual-phase MAX25202 is available. The MAX25202 operates at a fixed 400kHz switching frequency and can be synchronized to an external clock.

The controllers feature a power-OK monitor and undervoltage 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.
