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…

* For Constant Current, the board must be modified as described on page 8 of the user guide. * Streetlight applications require that the power supply designed to power an LED lamp must have high efficiency and at least an equivalent lifetime in order to guarantee maintenance-free operation during the life of the LED.

The UCC28600 evaluation module (EVM) is a 120-W off-line quasi-resonant flyback converter providing a 19.4-V regulated output at 6.2 A of load current, operating from a universal ac input.

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…

The LM5008 Step down switching regulator features all of the functions needed to implement low cost, efficient, Buck bias regulators. This high voltage regulator contains a 100V, 0.5A N-channel Buck switch.

The SSM2305 is a fully integrated, single-chip, mono Class-D audio amplifier that is designed to maximize performance for mobile phone applications. The application circuit operates from a single 2.5 V to 5.5 V supply and is capable of delivering 2.8 W of continuous output power with less than 10% THD + N driving a 4 Ω load from a single 5.0 V supply.

Whenever a lighting application, such as street lighting for example, requires an elevated number of LEDs, there are basically two solutions: the first is to connect all the diodes in series in a single "string"; the second is to place several strings in parallel with fewer elements in each one.

* 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.

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…

The VIPer53 combines an enhanced current mode PWM controller with a high voltage MDMesh Power Mosfet in the same package. VIPer53 is available in two different packages, DIP-8 and PowerSO-10. This reference board is an offline wide range power supply that incorporates VIPer53 and is set up for secondary regulation by driving the PWM controller through an optocoupler.
