The LTC1143LCS-ADJ is a dual step-down switching regulator controller designed by LT for high-efficiency power conversion. It features current mode operation for excellent transient response and maintains high efficiency over a wide load current range. The device supports automatic Burst Mode operation to preserve efficiency at low output currents.
Key electrical specifications include a wide input voltage range of 3.5V to 16V and a maximum switching frequency of 400kHz. It offers very low dropout operation with a 100% duty cycle. Standby current is low at 160μA per output under light load conditions. The controller is user-programmable for operating current levels via an external sense resistor.
This controller is suitable for applications requiring dual output voltages with high conversion efficiencies in a compact form factor. It is available in a narrow 16-pin SO package, designed for surface mounting.
Applications include personal digital assistants, notebook and palmtop computers, battery-operated digital devices, portable instruments, and DC power distribution systems.
The input voltage range is 3.5V to 16V.
The switching frequency is up to 400kHz.
The operating temperature range is 0°C to 70°C.
The LTC1143LCS-ADJ is available in a 16-SOIC package (0.154", 3.90mm Width).
The efficiency is over 95%.
The standby current is 160µA per output at light loads.
