Recently Added Designs
AC/DC and DC/DC Conversion > DC/DC SMPS - Single Output EVLMG1-250WLLC: 24V @ 10.4A, 360 ~ 440VDC In Manufacturer: STMicroelectronics

This demonstration board is a resonant LLC converter dedicated to any kind of industrial application where minimum size and high efficiency is required, based on MasterGaN1.

Lighting > LED Drivers - DC In DC994A: 350mA x 3 Ch, 3 ~ 40V in Manufacturer: Analog Devices Inc.

Demonstration circuit 994 features the LT3003 three channel LED ballaster with PWM in a 10-lead MSOP thermally enhanced MSE package. The demonstration circuit is designed to ballast three channels of LED current from 100mA to 350mA per channel. The PWM dimming function of the LT3003 eliminates the need for discrete MOSFETs. The LT3003 internally performs the level-shift required for non-ground re…

Audio Amplifiers SSM2315-EVALZ: 3.4 W @ 3 Ω, 2.5 ~ 5.5V in Manufacturer: Analog Devices Inc.

The SSM2315 is a fully integrated, single-chip, mono 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 3 W of continuous output power with less than 1% THD + N driving a 3 Ω load from a single 5.0 V supply.
