With just a Raspberry Pi Pico, an analog switch and an op amp, you can build a powerful SDR receiver covering the LW, MW and SW bands. Capable of receiving signals from halfway around the world.
A low-cost PD-powered reflow soldering heating plate that uses a cermet heater (MCH) instead of a PCB heating plate for heating. It has a USB Type-C input port and can be powered by a 60W (65W) PD power supply.
This document is an engineering report describing the design of a non-isolated, buck-boost LED driver (power supply) using the LYTSwitch family device LYT4313E.
The DER-357 provides a single 12 W triac dimmable constant current output. The main design goal is to achieve high efficiency to increase luminous efficiency and reduce size. This allows the driver to fit into the BR40 lamp and be as close to the production design as possible.
This document is an engineering report describing an isolated power factor dimmable LED driver (power supply) using the LYT4314E from the LYTSwitch family of devices. The DER-366 provides a single 20W (36 VTYPICAL) dimmable constant 550 mA current output over an input voltage range of 190 to 265 VAC. Key design goals are high efficiency to maximize efficacy and small size. This allows the driver to be installed into a PAR38 sized lamp as close as possible to the production design.
This document introduces a highly compact and cost-effective step-down power supply designed using the LYTSwitchTM-0 series device (LYT0006P).
The power supply can operate from an input voltage range of 90 to 264 VAC. The DC bus voltage is high enough to support a 54 V output when using a buck topology. In a buck converter, the output voltage must always be lower than the input voltage. In addition, the output voltage is also limited by the maximum duty cycle of LYTSwitch-0, which also requires that the input voltage must be higher than the output voltage.
This document is an engineering report describing the design of a non-isolated, step-down LED driver (power supply) using the LYTSwitch-4 series device LYT4312E.
DER-359 provides a single 8 W dimmable constant current output.
The main design goal is to achieve high efficiency to increase luminous efficiency and reduce size. This allows the driver to fit into the BR30 lamp and be as close to the production design as possible.
This document introduces a highly compact and cost-effective step-down power supply designed using the LYTSwitch-0 series device (LYT0006D).
The power supply can operate from an input voltage range of 90 to 132 VAC. The DC bus voltage is high enough to support a 38 V output when using a buck topology. In a buck converter, the output voltage must always be lower than the input voltage. In addition, the output voltage is also limited by the maximum duty cycle of LYTSwitch-0, which also requires that the input voltage must be higher than the output voltage.
