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 Converter) 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.
• Single Chip Current Mode Control IC • 60V, On-Chip DMOS Power Transistor • Thermal Protection • Over-Current Protection • 250kHz Operation • Output Rise and Fall Times - 10ns • On-Chip Reference Voltage - 5.1V • Slope Compensation • VDD Clamp Allows 10.8V to 60V Supply • Supply Current Does Not Increase When Power Device is On
HIP5061 Typical Application
• Distributed / Board Mounted Power Supplies • DC - DC Converter Modules • Voltage Inverters • Small Uninterruptable Power Supplies • Cascode Switching for Off Line SMPS
