Rugged Linear DC / DC Controller

Linear Technology Corporation (Linear Technology) rated operating temperature of 125oC introduced a wide range of general-purpose input and REG5601U datasheet and output voltage DC / DC Controller LT3724. LT3724 suitable for buck, boost, inverting, or with up to 100W output power SEPIC circuits. LT3724s power can be used 4V to 60V input supply voltage into a stable 1.23V to 36V output. Current mode of work with a variety of benefits, such as a wide range of voltage and REG5601U price and load current stability, accurate short-circuit protection and REG5601U suppliers and fast line and load transient response and so on. To simplify output noise filtering, reduce the size of inductors and capacitors, and improve efficiency, LT3724 at a constant 200kHz switching frequency. LT3724 is a single-chip solution for industrial, 12V and 42V automotive and heavy equipment, avionics and telecom power systems in a variety of applications such as power supply topology. LT3724 has a large N-channel MOSFET can be driven on-chip gate drive. The controller includes Burst Mode (Burst Modeò) work, the quiescent current to less than 100uA, while maintaining high efficiency at light loads. Slightly less than full load efficiency of 95%. In addition, the internal high voltage bias regulator allows for simple biasing and can be later to drive to increase efficiency. Other LT3724 features include precision undervoltage shutdown, 10uA shutdown current and programmable soft start to minimize overshoot at startup. LT3724 16-pin thermally enhanced TSSOP package, rated operating temperature range is-40oC to 125oC. 1,000-piece quantities starts at $ 3.10 per piece. Performance Summary: LT3724 4V to 60V wide input range of Up to 36V output voltage Buck, boost, SEPIC topology of the negative output or ± 1.3% reference voltage accuracy 200kHz fixed frequency operation Current mode Shutdown current is less than 10uA
