Boost regulator reduces component count
Boasting integrated power FETs, Elantec's EL7512CY is a single-chip synchronous boost DC/DC regulator that reduces component count and saves design time in LCDs and portable products.
Boasting integrated power FETs, Elantec's EL7512CY is a single-chip, synchronous boost DC/DC regulator that reduces component count and saves on design time when used in LCD displays and portable products such as digital cameras, test instruments and PDAs Available in the UK from DT Electronics, the device is packaged in a compact MSOP10 package and requires just a few external passive components to provide a complete DC/DC step-up (boost) convertor

Exar PowerBlox buck regulators feature extremely high current densities.
The regulator can be operated as high as 1.2MHz switching frequency, making it an attractive device for powering ADSL, USB modems.
When used to generate a +5V output from a 3.3V input, the EL7512CY can provide from 100 to 500mA of load current while operating at up to 90% efficiency.
Alternatively, operating from a 5V supply it can provide +12V at 100 to 300mA, again at 90% efficiency.
Just two external resistors are needed to set the desired output voltage.
In shutdown mode the device consumes just 3mA, and an external "enable" control turns the device on/off.
For safety and reliability, the device features a low battery output signal to warn when the input falls below a prescribed level.
A demo board is available from DT Electronics to facilitate designers with the opportunity to evaluate the EL7512CY for use in a wide range of products.
