No-Opto Isolated Flyback Converters

Jun 10th 2016
The no-opto isolated flyback parts from Linear need no opto-coupler or LT1431 shunt regulator for regulation. They sense the isolated output voltage directly from the primary-side waveform. This simplifies the design, allows for a smaller solution size and only requires one component crossing the isolation barrier. The load, ...

LTspice: Simple Steps for Simulating Transformers

Gabino Alonso - Strategic Marketing Engineer Jul 1st 2014
Here is the simple approach to simulate a transformer in LTspice IV: Draft an inductor for each transformer winding Couple them using a single mutual inductance (K) statement via a SPICE directive: K1 L1 L2 L3 1 The last entry in the K statement is the coupling coefficient, which can vary between 0 and 1, where 1 represents ...

Miniature Isolated Solution Using LT8301 and Coupled Inductor

Bryan Legates - Director of Design Engineering
Chen Zheng - Design Engineer Jun 19th 2014
Customers that require miniature solutions with only functional isolation often choose isolated modules. These solutions have very bulky form factors, and typically do not provide high power efficiency or a low no-load input current. In addition, the output voltages of these modules are usually unregulated, having large VOUT ...
