Analog Devices MAX17795
The MAX17795 is a high-efficiency, high-voltage, synchronous step-down DC-DC converter with integrated MOSFETs operating over an input voltage range of 3V to 80V. The device can deliver up to 5A current and generate output voltages ranging from 0.6V up to 90% of VIN. The device features a MODE/SYNC pin that can be used to program the device in forced pulse-width modulation (PWM) or switching frequency modulation (SFM) modes of operation and to synchronize the internal clock to an external clock.| Part No. | MAX17795 |
