Quick Detail:

Integrated Adjustable 6 Amp Synchronous Switcher

Description:

The EL7556D is an adjustable synchronous DC:DC switching regulator optimized for a 5V input and 1.0V-3.8V output. By combining integrated NMOS power FETS with a fused-lead package, the EL7556D can supply up to 6A continuous output current without the use of external power devices or discrete heat sinks, thereby minimizing design effort and overall system cost.

On-chip resistorless current sensing is used to achieve stable, highly efficient, current-mode control. The EL7556D also incorporates the VCC2DET function to directly interface with the Intel P54 and P55 microprocessors. Depending on the state of VCC2DET, the output voltage is internally preset to 3.5V or a user-adjustable voltage using two external resistors. In both internal and external feedback modes the active-high PWRGD output indicates when the regulator output is within ±10% of the programmed voltage. An onboard sensor monitors die temperature (OT) for overtemperature conditions and can be connected directly to OUTEN to provide automatic thermal shutdown. Adjustable oscillator frequency and slope compensation allow added flexibility in overall system design.

The EL7556D is available in a 28-pin SO package and is specified for operation over the full -40°C to +85°C temperature range.
