International Rectifier Introduces the IRS2795 Resonant Half-Bridge Control ICs

International Rectifier introduced the IRS2795(1,2)S resonant half-bridge control ICs, the industry’s first 8-pin resonant half-bridge control ICs for energy efficient Switch Mode Power Supplies (SMPS) used in LCD televisions and monitors, home theater systems, desktop computers, printers and game console applications.

The IRS2795(1,2)S resonant half-bridge control ICs offer a high level of programmability and protection. Features include programmable switching frequency up to 500 kHz with 50 percent fixed duty cycle, programmable soft start frequency and soft start time, and programmable deadtime for optimized Zero Voltage Switching (ZVS) under all load conditions to achieve high efficiency and low switching noise.

The IRS2795(1,2)S resonant half-bridge control ICs also offer over-current protection using the on-state resistance (RDS(on)) of the low-side MOSFET, eliminating the need for an additional current sense resistor. Other key features include floating channel bootstrap operation up to +600Vdc, micro-power start-up and ultra-low quiescent current, as well as user initiated micro-power “sleep mode”.
