Cherokee International (Tustin, CA) introduced its Tustin Series of non-isolated dc/dc surface-mount converters. The new LS20 models represent the most recent complement to the company's expanding line of board-mounted dc/dc offerings.
The Tustin Series power modules are designed for high-performance DSP and microprocessor circuits and system board-level applications. Cherokee claims that each module employs synchronous conversion along with advanced circuit techniques, high-frequency switching and high-density surface-mount packaging technology.
The LS20 power modules are available in either a 3.3V or 5.0V input. They have a 300A/uSec load transient response and measure 44.6mm x 12.7mm x 8.5mm. Other features include a single control pin for margining and on/off control and over-current protection. The converters require no external bias and are compliant with 73/23/EEC and 93/68/EEC directives.
The Tustin Series LS20 modules are available in small quantities priced at $49.00 each. Samples are currently available from stock.
