MAX17505 Datasheet | Maxim Integrated

Description The MAX17505/MAX17505S high-efficiency, highvoltage, synchro­nously rectified step-down converter with dual integrated MOSFETs operates over a 4.5V to 60V input. It delivers up to 1.7A and 0.9V to 90%VIN output voltage. Built-in pensation across the output voltage range eliminates the need for external ponents. The feedback (FB) regulation accuracy over -40NC to +125NC is ±1.1%. The device is available in a pact (4mm x 4mm) TQFN lead(Pb)-free package with an exposed pad. Simulation models are available. The device features a peak-current-mode control architecture with a MODE feature that can be used to operate the device in pulse-width modulation (PWM), pulse-frequency modulation (PFM), or discontinuousconduction mode (DCM) control schemes. PWM operation provides constant frequency operation at all loads, and is useful in applications sensitive to switching frequency. PFM operation disables negative inductor current and additionally skips pulses at light loads for high...
