LTC1772 - Constant Frequency Current Mode Step-Down DC/DC Controller In SOT-23

The LTC1772 is a constant frequency current mode stepdown DC/DC controller providing excellent AC and DC load and line regulation. The device incorporates an accurate undervoltage lockout feature that shuts down the LTC1772 when the input voltage falls below 2.0V.
The LTC1772 provides a 2.5% output voltage accuracy and consumes only 270A of quiescent current. For applications where efficiency is a prime consideration, the LTC1772 is configured for Burst Mode operation, which enhances efficiency at low output current. To further maximize the life of a battery source, the external P-Channel MOSFET is turned on continuously in dropout (100%dutycycle).In shutdown, the device draws a mere 8A. High constant operating frequency of 550kHz allows the use of a small external inductor.
The LTC1772 is available in a small footprint 6-lead SOT-23.
