The LM3450A evaluation board is designed to provide an AC to LED solution for a 30 W LED load. Specifically, it takes an AC mains input and converts it to a constant current output of 700 mA for a series string of 1 to 13 LEDs (maximum LED stack voltage of 45 V). There are two assembly versions designed to operate from two different nominal AC input voltages, 120 VAC or 230 VAC.

This document provides details of the vacuum cleaner evaluation board, including jumper settings, load connections, and device and software features. In terms of both hardware and software, the tool is ready for use in the development of universal motor driving based on phase angle control.

* 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.

This document describes how to design a 3-phase (106 ~ 848 VAC) power supply with the UC3845B PWM driver and the new STC04IE170 ESBT as main switch. It is associated with the release of the STEVAL-IPB001V1 demo board.

The controller utilizes a constant on-time control scheme which eliminates the need for external compensation components, allowing the power supply designer to minimize necessary board space and reduce costs.

The LM2771 is a switched capacitor step-down regulator that produces a 1.5V output without the use of an inductor. It is capable of supplying loads up to 250mA. The LM2771 operates with an input voltage from 2.7V to 5.5V, and requires only 3 low-cost ceramic capacitors.

The CC2500 is a low-cost 2.4 GHz transceiver designed for very low-power wireless applications. The circuit is intended for the 2400-2483.5 MHz ISM (Industrial, Scientific and Medical) and SRD (Short Range Device) frequency band.

Cypress EZ-USB® FX3™ (FX3) is an ARM-based controller designed to implement USB 3.0 peripherals. USB 3.0 offers the SuperSpeed signaling rate of 5 gigabits per second, which is 10 times greater than the high-speed signaling rate of 480 megabits per second. Because FX3 is USB 3.0 compliant, in addition to operating at the new SuperSpeed data rate, it can also operate at the High-Speed and Full-Spe…

Demonstration circuit 2079A is a 40VIN, 40VOUT LED driver. It generates its own PWMOUT waveform from its internal PWM generator for accurate PWM dimming with up to 33:1 brightness ratio. It accepts an input voltage from 5V to 30V and drives up to 32V of LEDs at 650mA (when PVIN is less than VLED). DC2079A features both PWM and analog dimming of the LED string. It has an OPENLED flag that indicate…

The SSM2377 is a fully integrated, high efficiency, Class-D audio amplifier. It is designed to maximize performance for mobile phone applications. The application circuit requires a minimum of external components and operates from a single 2.5 V to 5.5 V supply. It is capable of delivering 2.5 W of continuous output power with
