The circuit shown here is a step down converter which can convert an input voltage varying from 8V to 28V to 5V. The circuit is based on TPS54202, which is a 2A synchronous buck converter. This IC has several features such as over-voltage protection and peak current mode...

A lot of project are battery powered and some of them need dual battery links. Robert on hackaday.io had shared his new project that shed light on this issue. He built an load sharing addon board with the ability to charge the battery while the project is operating. Many Chinese...

LTC3897 is a multiphase synchronous boost DC/DC controller with input surge stopper and ideal-diode controller. The boost controller drives two N-channel power MOSFET stages out-of-phase to reduce input and output capacitor requirements, enabling the use of smaller inductors versus...

T A Babu @ edn.com discuss about a protection circuit for boost converters. Boost converters are particularly susceptible to output shorts as there is a DC path from input to output. Usually a fuse, resettable or non-resettable, protects the system, but it is not always accurate or...

The Step-Up DC-DC Converter project provides 28V, 175mA output with input of 12V DC. The MC34063A IC is heart of the project from On semiconductor. The MC33063A is a monolithic control circuit containing the primary functions required for DC-DC converters. This device consist of an...

The board built around LM2575-ADJ from Texas instruments. A 1.0 A output current capability power supply that features an adjustable output voltage, This regulator board delivers 1.0 A into 1.2 V to 35 V output. The input voltage ranges from roughly 8.0 V to 40 V. In order to achieve...

This circuit can produce an output of 3.3V and 1A current continuously for a voltage input varying from 2.5V to 4.2V. The LTC3441 is a high efficient buck boost converter which plays a vital role in portable instrumentation because of its fixed frequency operation. This circuit...

12V To 24V Booster is based on LM2588 IC from Texas Instruments. The LM2588 regulator integrated circuit specifically designed for fly-back, step-up (Boost) , and forward converter. The board provides 24V DC 1A DC output, Input 8V to 16V DC. Board has minimum components, screw...
