STEVAL-ISA035V1: 4.2W, 12V @ 350mA, 85 ~ 265 Vin

Manufacturer: STMicroelectronics

Many appliances today use non-isolated power supply to furnish low output power required to run a micro, LED display, and a few relays or AC switches. This type of power supply has a single rectifier so as to reference the neutral to output ground in order to fire TRIACs or AC switches.

TPS54350EVM-235: 3.3V @ 3A, 6 ~ 18 Vin

Manufacturer: Texas Instruments

The TPS54350 dc/dc converter is designed to provide up to 3-A output from a nominal 12-V (6-V to 18-V) input voltage source. Rated input voltage and output current range is given in Table 1−1. This evaluation module is designed to demonstrate the small PCB areas that may be achieved when designing with the TPS54350 regulator and does not reflect the high efficiencies that may be achieved when des…

STEVAL-ISA018V1: 150W, 24V @ 6A, 85~185/185~265VAC

Manufacturer: STMicroelectronics

This user manual describes a high efficiency solution for industrial power supplies with a continuous output power of 150 W and peak power up to 240 W. It takes advantage of the resonant approach to minimize switching losses, resulting in higher than 90% efficiency. The topology is based on half-bridge and operated in a resonant fashion by means of a resonant LC tank, driven by the L6599 dedicate…

AN954: Off-Line Capacitive Power Supply

Manufacturer: Microchip Technology

* From page 10 of AN954:

Figure 10 shows a capacitive power supply with several UL considerations designed in. A fuse is added to protect the circuit during an over-current condition.

Adding R2 in parallel with C1 creates a filter that will attenuate EMI from traveling back onto the line. A varistor, or MOV, provides transient protection.

Advantages of C…

STEVAL-ISA019V2: 80W, 24V @ 3.3A, 160 ~ 550VAC

Manufacturer: STMicroelectronics

The purpose of this application note is to explain the design of an 80 W 3-phase auxiliary power supply for motor drives and welding applications. To reach a high level system in terms of both efficiency and cost, the L6565 PWM controller has been selected as well as the STC04IE170HV as the main switch. The combination of these STMicroelectronics parts provides a highly efficient solution for hig…
