The supply range spans 5V to 30V at Vcc, making it suitable for intermediate bus rails or multi-cell battery inputs without a pre-regulator. It integrates a synchronous rectifier driver, which improves efficiency at low output voltages by replacing the freewheeling diode with a second MOSFET. The switching frequency is pin-selectable between 150kHz and 300kHz, giving the layout engineer a trade-off between inductor size and switching losses. ## Control features and temperature grade The controller includes Enable, Pulse Skipping, and Soft Start control features. Pulse skipping reduces switching losses at light loads, while the soft-start pin sets the output ramp time to limit inrush. Maximum duty cycle is 96%, which allows the output to track close to the input rail — useful when the input is a nominally 5V rail and the output must hold regulation through brownout conditions. ## Sourcing and availability This is an active, in-production part from Analog Devices. The tube package (16-SOIC) is the standard delivery format for this order code.","metaTitle":"MAX797HESE+ Analog Devices Buck Controller, 5V-30V, 16-SOIC","metaDescription":"MAX797HESE+ step-down buck controller from Analog Devices. 5V to 30V supply, 150/300kHz switching, synchronous rectifier, 16-SOIC.
