Renesas Introduces Rad-Hardened 1-Chip Sync Buck LDO Regulator for Satellite

The ISL70005SEH rad-hard dual output POL regulator combines 95 percent high efficiency with the synch buck regulator and a low 75mV dropout on the LDO regulator. The device enables easier thermal management for systems with 3.3V or 5V power buses and can support 3A continuous output load current for the buck regulator and ±1A for the LDO. The buck regulator uses a voltage mode control architecture
