HIP5062

® No T ent UC OD lacem R E P Re p LET ded O n S O B m me o c e R HIP5062 August 1998 File Number 3208.2 Power Control IC Single Chip Dual Switching Power Supply The HIP5062 is a complete power control IC, incorporating two high power DMOS transistors, CMOS logic and two low level analog control circuits on the same Intelligent Power IC. Both the standard “Boost” and the “SEPIC” (SingleEnded Primary Inductance Converter) power supply topologies are easily implemented with this single control IC. Special power transistor current sensing circuitry is incorporated that minimizes losses due to the monitoring circuitry. Moreover, over-temperature and over-voltage detection circuitry is incorporated within the IC to monitor the chip temperature and the actual power supply output voltage. These circuits can disable the drive to the power transistor to protect both the transistor and, most importantly, the load from over-voltage. As a result of the power DMOS transistor’s current and voltage capability (5A and 60V), multiple output power supplies with total output power capability up to 100W are possible.
