MAX17290/MAX17292 EVALUATION KIT AVAILABLE 2.5V to 36V, 2.5MHz, PWM Boost Controller with 4µA Shutdown Current and Reduced EMI General Description 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.
