The L4978 is a 2A monolithic dc-dc converter, step- down , operating at fix frequency continuous mode. It is realised in BCD60 II technology, and it’s available in two plastic packages, MINIDIP and SO16L.
One direct fixed output voltage at 3.3V ±1% is available, adjustable for higher output voltage values, till 40V, by an external voltage divider.
The operating input supply voltage ranges from 8V to 55V, while the absolute value, with no load, is 60V. New internal design solutions and superior technology performance allow to generate a device with improved efficiency in all the operating conditions and with reduced EMI due to an innovative internal driving circuit, and reduced external component counts.
