Datasheet Summary
Radiation Hardened Single/Dual Phase Current Mode PWM Controller
The ISL73847SLH is a synchronous buck controller that can operate as a single or dual-phase controller. It works with the ISL71441SLH (half-bridge GaN FET driver) to generate point-of-load voltage rails for mercial 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...
