HP1000
DC-DC Digital Power Controller
The HP1000 is a versatile digital controller designed for high-density, high-efficiency DC-DC power conversion, with PMBusTM Revision 1.2 compliant interface. This device provides advanced power control solutions targeted at isolated and non-isolated DC-DC secondary-side applications, including fullbridge/half-bridge isolated converters, open-loop LLC converters, multi-phase buck converters, etc.
The HP1000 offers extensive programmability of integrated digital compensators, fast input line feedforward, PWM output types and timing, constant current mode, as well as soft-start/stop sequences and synchronization. Additionally, it provides flexible protection features including over-voltage protection (OVP), short-circuit protection (SCP), reverse current protection (RCP), over-temperature protection (OTP), and ensuring a robust power management solution. The HP1000 employs a flexible state machine architecture programmed via intuitive GUI. This userfriendly interface reduces design cycle time while producing a robust, hardware-coded system embedded in the built-in EEPROM. The HP1000 is available in 4 mm x 4 mm QFN-24L.
