The LTC1149CN-5 from Analog Devices is a family of synchronous step-down switching regulator controllers. These devices feature automatic Burst Mode operation to maintain high efficiencies at low output currents. They drive external complementary power MOSFETs at switching frequencies up to 250kHz using a constant off-time current-mode architecture.
Designed for operation at input voltages from dropout to 48V (60V absolute maximum), the LTC1149 series maintains high efficiency over a wide current range. It includes features like logic-controlled micropower shutdown and short-circuit protection. The controller operates with very low dropout, enabling 100% duty cycle operation.
This specific model, the LTC1149CN-5, is configured for a 5V output voltage. It is available in a 16-pin DIP package, suitable for through-hole mounting. The device operates within a temperature range of 0°C to 70°C.
Typical applications include notebook and palmtop computers, portable instruments, battery-operated digital devices, industrial power distribution, avionics systems, and telecom power supplies.
