Description

The HIP5060 is a complete power control IC, incorporating both the high power DMOS transistor, CMOS logic and low level analog circuitry 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 HIP5060 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 (10A and 60V), power supplies with output power capability in HIP5060 up to 100 watts are possible.
