The advantages of a switch-mode power supply (SMPS) are just too great to ignore. Efficiency is the primary benefit, with efficiencies over 90% for many designs. Such as online design software.

The device is a high-voltage converter that smartly integrates an 800 V avalanche rugged power MOSFET with PWM current-mode control. The power MOSFET with 800 V breakdown voltage allows extended input voltage range to be applied, as well as to reduce the size of the DRAIN snubber circuit. This IC is capable of meeting the most stringent energy-saving standards as it has very low consumption and operates in pulse frequency modulation under light load. The Zero-Power mode (ZPM) feature enables the IC to work in an idle state, where the system is totally shutdown. An MCU can be easily connected to the IC for smart ZPM management and it can be supplied by the IC itself during the idle state.

The design of flyback, buck and buck boost converters is supported. The integrated HV startup, sense FET, error amplifier and oscillator with jitter allow a complete application to be designed with a minimum component count. In flyback non isolated topology, a negative output voltage is easily set thanks to the integrated error amplifier with separate ground.

The results are the needed capacitance value and equivalent series resistance (ESR) of the output capacitor. Bad boys free download. VIPer selection – step 2 1.

Device selection: the software automatically selects the device based on the output power. Operating mode: discontinuous mode is set by default but the user can change it to continuous.

Maximum ambient temperature: has an impact on power dissipation, thus on the converter’s power capability. Case-ambient thermal resistance: the default value can be decreased and power dissipation improved by providing a heat sink.

AC/DC input – step 3 1. Input voltage range selection: – 110 V range – 230 V range – Full range 2. Input ripple selection 3. Hold-up cycles selection 4. Line frequency selection: 50 or 60 Hz Output inductance selection – step 4 In the inductor setting window, the user can change the default inductor by either choosing another inductor in a given database, or directly entering the inductance value, ESR, ISAT and parasitic capacitance of the custom inductor.

The inductor is used for energy storage, and its selection depends on the output power and on the power switch. A custom ferrite inductor must be used in case of high output power converters. For low output power converters an axial insulated inductor can be used.

The drawback of this low cost solution is the higher series resistance that could affect the efficiency of the converter. The inductance value determines whether the circuit operates in discontinuous mode or in continuous mode for a given output current.
