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.
