The LTC1772BIS6 is a constant frequency current mode step-down DC/DC controller from LT, designed for excellent AC and DC load and line regulation. It operates with a wide input voltage range from 2.5V to 9.8V and can provide an output voltage down to 0.8V.
Key features include a high constant operating frequency of 550kHz, which allows for the use of small external inductors. The device boasts high efficiency of up to 94% and a low quiescent current of 270μA, drawing only 8μA in shutdown mode. It also incorporates an accurate under-voltage lockout feature that shuts down the device when the input voltage falls below 2.0V.
This controller is available in a tiny 6-lead TSOT-23 package, making it suitable for space-constrained applications. The current mode operation ensures excellent transient response for both line and load.
Applications include one or two lithium-ion-powered devices, cellular telephones, wireless devices, portable computers, and distributed power systems requiring 3.3V, 2.5V, or 1.8V outputs.
The input voltage range is 2.5V to 9.8V.
