Voltage Regulators
Until Willow Garage was acquired, there was work as a Web Robotics Engineer. This title reflects a role as a full-stack engineer focused on real-time, distributed robot control. Notable projects include an XML-RPC server and client for Node.js, a deprecated...
Switching Regulator Circuit
This example presents a switch DC regulated power supply circuit designed for buck-mode +5V applications. It consists of a power supply circuit, an impulsator, a voltage sampling or pulse width modulation circuit, and a buffering driver circuit, as illustrated in...
How to Boost Efficiency at Low Loads
Small additional circuitry during standby can significantly enhance efficiency. In a modern vehicle, multiple microcontrollers are required to support safety, navigation, entertainment, and comfort electronics.
The integration of additional circuitry during standby mode in automotive applications is crucial for optimizing power...

A voltage regulator is designed to provide a fixed voltage to any load. This inherently means it must supply the necessary current through that load to satisfy Ohm's Law, I = V/R. As the resistance (R) approaches zero, such as...
Auto Fuse for power supply
The power supply, with electronic stabilization - mainly those of laboratories - should be protected from overcurrent that emanates from short-circuits, erroneous association, or damage of repaired appliances. The circuit offers effective protection in power supply with output voltage up...
0-30 VDC Stabilized Power Supply with Current Control 0.002-3 A
The circuit begins with a step-down mains transformer featuring a secondary winding rated at 24 V/3 A, which connects across the input points at pins 1 and 2. The quality of the output supply is directly related to the transformer's...
5V USB interface power supply / charger circuit
The USB charger power supply is designed for use in MP3 and MP4 chargers. It accepts an input of AC 160-240V at 50/60Hz and has a rated output of DC 5V at 250mA. For applications requiring a long-term higher current...
2 watt switching power supply
This compact switching power supply utilizes a Schmitt trigger oscillator to control a switching transistor, which provides current to a small inductor. When the transistor is activated, energy accumulates in the inductor, and this energy is subsequently released into the...
Changhong DVB-2000 digital satellite receiver switching power supply circuit
The Changhong DVB-2000 digital satellite receiver features a switching power supply circuit. This circuit primarily comprises a power input section, an oscillation switching circuit, and a DC output section. The power input circuit receives 22V AC from a step-down transformer,...
