AN938 APPLICATION NOTE DESIGNING WITH L4973, 3.5A HIGH EFFICIENCY DC-DC CONVERTER by N. Trii and G. Gattavari
INTRODUCTION The L4973 family is a 3.5A monolithic dc-dc converter, step- down topology, operating in continuous mode. It is realized in BCD60 II technology, and it’s available in two plastic packages, POWERDIP18(12+3+3) and SO20L (12+4+4). Two versions are available, one fixing the output voltage, without any voltage divider, at 3.3V, and the second at 5.1V. Both the regulators can control higher output voltage values, by using an external voltage divider. The operating input supply voltage is ranging from 8V to 55V, while the absolute value, with no...
