An ideal diode uses a low on-resistance power switch, commonly a MOSFET, to mimic the unidirectional current flow behavior of a diode, but without the lossy diode voltage drop penalty. With an additional back-to-back MOSFET and control circuitry, the solution can offer even more system control...
Analog Devices' ideal diode bridge controllers replace the four diodes in a full-wave bridge rectifier with a low loss MOSFET to drastically reduce power dissipation, heat generation, and voltage drop
As a result, a voltage drop loss which occurs in the conventional semiconductor diode caused by the offset when the diode is electrified in forward direction can be reduced and accordingly a power loss can be reduced.;COPYRIGHT: (C)2002,JPO 展开 ...
The LTC®4415 contains two monolithic PowerPath ideal diodes, each capable of supplying up to 4A with typical forward conduction resistance of 50mΩ. The diode voltage drops are regulated to 15mV during forward conduction at low currents, extending the power supply operating range and ensuring ...
Ideal Diode Controllers In the power domain high efficiency is critical. Power losses must be minimized. Many manufacturers have adopted a strategy that uses a power MOSFET as a diode and controls the voltage drop across it. The integrated circuit that serves this function h...
