The MAX17290 high-efficiency, synchronous step-up DC-DC controllers operate over a 4.5V to 36V input voltage range with 42V input transient protection. The input operating range can be extended to as low as 2.5V in Bootstrapped mode.

The MAX17290 and MAX17292 use a constant-frequency, pulse-width modulating (PWM), peak current-mode control architecture. There are multiple versions of the devices offering one or more of the following functions: a synchronization output (SYNCO) for 180° out-of-phase operation, an overvoltage protection function using a separate input pin (OVP), and a reference input pin (REFIN) to allow on-the-fly output voltage adjustment.

The MAX17290 and MAX17292 operate in different frequency ranges. All versions can be synchronized to an external master clock using the FSET/SYNC input.

The devices are available in a compact 12-pin (3mm x 3mm) TQFN and 10-pin μMAX packages. Both packages have exposed pads. -40°C to +85°C Operation.
