The MAX17290/MAX17292 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.

Product Detail

The MAX17292 evaluation kit (EV kit) is a fully assembled and tested PCB that contains a 16W DC-DC boost converter for battery-operated, harsh environment, front-end preboost applications. The MAX17292 integrates a low-side FET driver and current-mode, control-loop circuitry for output-voltage regulation, making it ideal for boost or SEPIC converters. The MAX17292’s integrated driver switches at 2.2MHz. The device can be synchronized with an external clock source within the 1MHz to 2.5MHz range.

.

The EV kit operates from a DC supply voltage of 3V up to 8V. The EV kit can withstand a 16V line transient condition. The EV kit demonstrates the device features, such as dynamic adjustable output voltage, external clock synchronization, two-phase operation configurability, cycle-by-cycle current limit, hiccup mode, and thermal shutdown. The boost converter regulates 8V and can supply a current up to 2A. The EV kit also demonstrates a reference MAX17292 design for battery-operated, harsh environment applications.
