Description

The LTC1574CS is one member of the LTC1574 family which is designed as the high efficiency step-down DC/DC converter with internal schottky diode that can be used in (1)inverting converters; (2)step-down converters; (3)memory backup supply; (4)portable instruments; (5)battery-powered equipment; (6)distributed power systems.

Features of the LTC1574CS are:(1)high efficiency: up to 94%; (2)usable in noise-sensitive products; (3)peak inductor current independent of inductor value; (4)short-circuit protection; (5)internal low forward drop schottky diode; (6)only three external components required; (7)wide vin range: 4V to 18.5V (absolute maximum); (8)low dropout operation; (9)low-battery detector; (10)pin selectable current limit; (11)internal 0.9W power switch: VIN = 12V; (12)standby current: 130mA; (13)active low micropower shutdown.

The absolute maximum ratings of the LTC1574CS can be summarized as:(1)input supply voltage (pin 5):-0.3V to 18.5V;(2)switch current (pin 3, 14):1 A;(3)switch voltage (pin 3, 14):VIN-18.5 V;(4)operating temperature range:0°C to 70°C;(5)junction temperature:125°C;(6)storage temperature range:-65°C to 150°C;(7)lead temperature (soldering, 10 sec):300°C.
