The LTC1772IS6#PBF from LT is a constant frequency current mode step-down DC/DC controller designed for efficient power management. It provides excellent AC and DC load regulation.
Key features include high efficiency up to 94% and a wide input voltage range from 2.5V to 9.8V. The controller operates at a constant frequency of 550kHz, allowing for the use of small external inductors. It also incorporates Burst Mode operation for enhanced efficiency at light loads and a low dropout feature with 100% duty cycle.
This device is housed in a compact 6-lead SOT-23 package, suitable for surface mount applications. It includes an accurate undervoltage lockout feature that shuts down the device when the input voltage falls below 2.0V. The quiescent current is a low 270µA, and in shutdown mode, it draws only 8µA, further conserving battery life.
Applications include one or two lithium-ion-powered devices, cellular telephones, wireless modems, portable computers, and distributed 3.3V, 2.5V, or 1.8V power systems.
