DLA has successfully evaluated the SMD 5962-20208 devoted to ST MICROELECTRONICS Rad-hard synchronous step-down regulator RHRPMPOL01
The ST MICROELECTRONICS RHRPMPOL01 is a single-phase, step-down monolithic switching regulator with high precision internal voltage reference and integrated power MOSFETs for synchronous conversion. The device has been developed using SOI technology that offers good performance against SEL effect.
The regulator converts 3.0 V to 12 V input voltage to 0.8 V to (0.85xVIN) output voltage. It has been designed to supply Field-Programmable Gate Arrays (FPGA), Digital Signal Processing (DSP), MCU and (Application-Specific Integrated Circuits) ASICS in general for space applications.
The controller is based on peak current mode architecture, which ensures a fast load transient response and very stable switching frequency. An embedded integrator compensates the DC voltage error due to the output voltage ripple. The fault management consists of not-latched output overvoltage protection, overcurrent protection and auto recovery thermal protection.
