150V synchronous step-down DC/DC includes surge protection
https://www.electronics-lab.com/150v-synchronous-step-dcdc-includes-surge-protection/
Linear Technology designed the LTC3895 to be a non-isolated DC/DC controller with a high input voltage capability that can eliminate the need for surge suppression and operate continuously with a high input voltage. The synchronous step-down switching regulator controller drives an all N-channel MOSFET power stage. Its 4V to 140V (150V abs. Max.) input voltage […]
LTC4380 – Low Quiescent Current Surge Stopper
https://www.electronics-lab.com/48785-2/
The LTC4380 is an ultralow quiescent current (IQ) surge stopper, providing compact overvoltage and overcurrent protection for always-on 4V to 72V electronics in automotive, industrial and avionic systems. The LTC4380 replaces traditional shunt circuits composed of bulky inductors, capacitors, transient voltage suppressors (TVS), and fuses with a simple IC and series N-channel MOSFET solution, saving […]
