The RH3845 is a high voltage, synchronous, current mode controller used for medium to high power, high efficiency supplies. It offers a wide 4V to 60V input range (7.5V minimum start-up voltage). An onboard regulator simplifies the biasing requirements by providing IC power directly from VIN.
Light load efficiency is also improved with the reverse inductor current inhibit function which supports discontinuous operation. BurstMode® is not available in the space version of the part.
Additional features include adjustable fixed operating frequency that can be synchronized to an external clock for noise sensitive applications, gate drivers capable of driving large N-channel MOSFETs, a precision undervoltage lockout, short-circuit protection and a programmable soft-start.
