RDK-839 is a 12 W Power Supply for Appliances, Auxiliary Power Supplies with a 85 VAC – 265 VAC input; 12 V, 1 A output using TinySwitch-4 IC (TNY288PG)

The STEVAL-ISA180V1 evaluation board implements a wide mains range flyback isolated converter (12 V - 0.6 A), developed for general purpose applications.

In standby mode it is often required that the equipment input power is as low as possible, which means reducing the input power of the auxiliary power supply, in no-load or light-load conditions.

The STEVAL- ISA032V1 forward converter demonstration board is a power supply based on the primary controller L5991 and the STP10NK60Z N-channel 600 V power MOSFET. It is designed to be suitable to supply power to the electronic fiscal cash register (EFCR) demonstration board STEVAL-IPC001V1.

This demonstration board is based on the new VIPER17 device and implements a standard single-output isolated flyback converter operating at fixed frequency that can be 115 kHz or 60 kHz.

This evaluation board is an AC-DC adapter for consumer equipment, typically implemented as an external unit.

This application note describes a low power, (output power of 4.1W) general purpose adapter which is able to handle a wide range input voltages (88VAC to 265VAC). The adapter (Order Code STEVAL-ISA011V1) is based on the Viper12A monolithic device that has the power switch as well as the basic control function needed to implement a current mode flyback converter.

The VIPer22A off-line SMPS primary switcher combines a dedicated current mode PWM controller with a high voltage Power MOSFET on the same silicon chip and its switching frequency is internally fixed at 60 kHz. The feedback path of the power supply includes an optocoupler for secondary regulation and galvanic isolation between primary and secondary sides. The output voltage is regulated at 12V wit…

This application note describes the characteristics and features of a 130 W demonstration board (EVL130W-SL-EU), tailored on an LED power supply specification for street lighting.

This kit includes a universal input, 12 V, 1 A flyback power supply using a TNY278P device from the TinySwitch-III family of ICs. It contains the complete specification of the power supply, a detailed circuit diagram, the entire bill of materials required to build the supply, extensive documentation of the power transformer, along with test data and oscillographs of the most important electrical …
