The LTC1771EMS8#PBF is a high-efficiency step-down DC/DC controller designed for battery-powered applications. It operates over a wide input voltage range of 2.8V to 20V and can provide output voltages from 1.23V to 18V, with output currents up to 5A. The device features a very low standby current of 10mA and can achieve efficiencies exceeding 93%. It supports current mode operation for improved transient response and includes short-circuit protection. The LTC1771 also offers a defeatable Burst Mode operation for enhanced efficiency at low loads and a micropower shutdown mode that reduces supply current to 2mA. The controller is available in a compact 8-lead MSOP package, making it suitable for space-constrained designs. Typical applications include cellular phones, wireless modems, and portable instruments.
