HIP5061

7A, High Efficiency Current

Mode Controlled PWM Regulator

Description

The HIP5061 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. The

standard “Boost”, “Buck-Boost”, “Cuk”, “Forward”, “Flyback”

and the “SEPIC” (Single-Ended Primary Inductance Con-

verter) power supply topologies may be implemented with

this single control IC.

Over-temperature and rapid short-circuit recovery circuitry is

incorporated within the IC. These protection circuits disable

the drive to the power transistor to protect the transistor and

insure rapid restarting of the supply after the short circuit is

removed.

As a result of the power DMOS transistors current (7A at 30%

duty cycle, 5A DC) and 60V capability, supplies with output

power over 50W are possible.
