HIP5062

Power Control IC Single Chip Dual Switch-

ing 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” (Single-

Ended 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.
