The LTC1779ES6 is a constant frequency, current mode step-down DC-DC converter from Linear Technology, housed in a compact 6-lead ThinSOT package. This device is designed for applications requiring efficient power conversion, offering up to 250mA of output current.
Key electrical specifications include a wide input voltage range of 2.5V to 9.8V and high efficiency up to 94%. It operates at a constant frequency of 550kHz, allowing for the use of small external inductors. The converter features current mode control for excellent load and line regulation, and incorporates an under-voltage lockout feature that shuts down the device when the input voltage falls below 2V.
For applications prioritizing efficiency at light loads, the LTC1779ES6 is configured for Burst Mode operation. In dropout conditions, the internal P-channel MOSFET is turned on continuously, enabling 100% duty cycle operation to maximize battery life. In shutdown mode, the device consumes a mere 8µA.
The LTC1779ES6 is suitable for various portable applications, including cellular telephones, wireless modems, and portable computers. Its low profile (1mm) ThinSOT package makes it ideal for space-constrained designs. The device operates within an ambient temperature range of -40°C to 85°C.
