| Description | 2A STEP DOWN SWITCHING REGULATOR |
|
|
The L4978 is a step down monolithic power switching regulator delivering 2A at a voltage between 3.3V and 50V (selected by a simple external divider). Realized in BCD mixed technology, the device uses an internal power D-MOS transistor (with a typical Rdson of 0.25Ω) to obtain very high efficency and high switching speed. L4978 (Minidip) L4978D (SO16) A switching frequency up to 500KHz is achievable (the maximum...
