Design Note DN 201301 V1. January 2013 Inductor copper loss The inductor RMS current. As told at the beginning of this section, the converter operates in discontinuous mode when low current is drawn by the load, and in continuous mode at higher load. V120mA switch mode power supply circuit. Transformer less switch mode power supplies have become very popular these days. The circuit shown below is of a 12V120mA. LT3800 1 3800fc TYPICAL APPLICATION FEATURES APPLICATIONS DESCRIPTION HighVoltage Synchronous Current Mode StepDown Controller The LT3800 is a 200kHz xed. V power MOSFET, oscillator, OnOff control for highest efficiency at light load, a high voltage switched current source for self biasing, frequency jittering, fast cycle by cycle current limit, hysteretic thermal shutdown, and output and input overvoltage protection circuitry onto a monolithic IC. Link. Switch TN2 devices feature improved accuracy of feedback pin regulation 1. Discontinuous Current Mode Boost Converter' title='Discontinuous Current Mode Boost Converter' />Link. Switch TN. Link. Switch TN2 ICs consume very little current in standby resulting in power supply designs that meet all no load and standby specifications worldwide. MOSFET current limit modes can be selected through the BYPASS pin capacitor value. The high current limit level provides maximum continuous output current while the low level permits using very low cost and small surface mount inductors. A full suite of protection features enable safe and reliable power supplies protecting the device and the system against input and output overvoltage faults, device over temperature faults, lost regulation, and power supply output overload or short circuit faults. As mentioned at the beginning of this section, the converter operates in discontinuous mode when low current is drawn by the load, and in continuous mode at higher.
