The MAX25200 is a high-performance, current-mode PWM controller with 1.5μA (typ) shutdown current for boost converters with a wide input voltage range. The 4.5V to 36V input operating voltage range makes these devices ideal in automotive applications, such as front-end preboost or general-purpose SEPIC or flyback power supplies. An internal low-dropout regulator with a 5V output voltage enables the MAX25200 to operate directly from an automotive battery input. The input operating range can be extended to as low as 1.8V after startup.
The MAX25200'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.
The device features a power-OK monitor and undervoltage lockout. Protection features include cycle-by-cycle current limit and thermal shutdown. The MAX25200 operates over the -40°C to +125°C automotive temperature range.
