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.

* 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…

The L5986 is a step-down switching regulator with 3.0 A (minimum) current limited embedded power MOSFET, so it is able to deliver up to 2.5 A current to the load depending on the application conditions.

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.

The new VIPer17 device integrates in the same package two components: an advanced PWM controller built in BCD6 technology and an 800 V avalanche rugged vertical power MOSFET. The device is suitable for off line power converter operating both, with wide range input voltage (85 VAC - 270 VAC) up to 7 W or with single range input voltage (85 VAC - 132 VAC or 175 VAC – 265 VAC). With European range i…

This demonstration board is based on the new VIPer17H device, that is a converter that offers in one package a PWM controller built in BCD6 technology and a 800 V avalanche rugged vertical power section.

The TPS40200EVM-001 evaluation module (EVM) uses the TPS40200 nonsynchronous buck converter to provide a resistor-selected 3.3-V output voltage that delivers up to 2.5 A from a 12-V input bus. The EVM operates from a single supply and uses a single P-channel power FET and Schottky diode to produce a low-cost buck converter. The part operates at a 300-kHz clock frequency with provision for externa…

The Texas Instruments TPS62050 and TPS62052 evaluation modules (EVM) for low-power, high-efficiency, step-down converters help designers evaluate these devices. The EVMs make it possible to evaluate different modes of the devices as well as the device performance.

The TPS6205xEVM is available as the TPS62050 adjustable version set to 3.3 V and the TPS62052 1.5-V fixed version.
