7A, High Efï¬ciency 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 âBoostâ, âBuck-Boostâ, âCukâ, âForwardâ, âFlybackâ
and the âSEPICâ (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.
