The LTC1772IS6#TRPBF from LT is a constant frequency current mode step-down DC/DC controller designed for efficient power conversion. It achieves high efficiency of up to 94% and supports a wide input voltage range from 2.5V to 9.8V.
This controller operates at a constant frequency of 550kHz, enabling the use of small external inductors. It features low quiescent current of 270µA and a shutdown mode that draws only 8µA, making it suitable for battery-powered applications. The device also includes an accurate undervoltage lockout feature and provides ±2.5% output voltage accuracy.
The LTC1772IS6#TRPBF is available in a compact 6-lead SOT-23 package, suitable for surface mount applications. Its current mode operation ensures excellent line and load transient response. Burst Mode operation is supported for enhanced efficiency at light loads.
Typical 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.
