ISL73847M Radiation Tolerant Single/Dual-Phase Current Mode PWM Controller Datasheet The ISL73847M is a synchronous buck controller that can operate as a single or dual-phase controller. It works with the ISL71441M (half-bridge GaN FET driver) to generate point-of-load voltage rails for commercial space applications. It accepts an input voltage range of 4.5V to 19V with a programmable PWM output switching frequency between 250kHz and 1.5MHz with a single resistor. The output can regulate a voltage upwards of 600mV and is limited on the top end by the minimum off time and selected switching frequency. The wide input voltage range makes it a suitable power supply option for a high-current FPGA core and other general-purpose power solutions.
