Converters вЂ“ Design Note 1016

Introduction
Small, high efп¬Ѓciency DC/DC converters are critical to
the design of leading-edge electronics. Achieving high
accuracy and efп¬Ѓciency traditionally means adding extra
components, complexity, and size. Not so with the LT3837.
This п¬‚yback controller serves 10W to 60W isolated applications with high performance, simplicity, small size,
and a minimum component count. blanking yields a high performance loop that is easy to
compensate. High-Efп¬Ѓciency Controller Capabilities
The LTВ® 3837 operates from a 4.5V to 20V input, but the
converter input range can be extended upwards by using
a VCC regulator and/or a bias winding on the transformer.
It also provides a synchronous rectiп¬Ѓer output with
adjustable timing to optimize efп¬Ѓciency and enhance
cross-regulation in multiple-output supplies. 3.3V, 10A Converter Operates from a 9V to18V
Source
The circuit shown in Figure 1 is a п¬‚yback design for a 3.3V,
10A output from a 9V to 18V input with a minimum of
external components. The LT3837 samples the voltage on
the primary winding during the п¬‚yback interval to provide
superb regulation. Figure 2 shows ruler-п¬‚at regulation at …
