The LTC®1872 is a constant frequency current mode stepup DC/DC controller providing excellent AC and DC load and line regulation. The device incorporates an accurate undervoltage lockout feature that shuts down the LTC1872 when the input voltage falls below 2.0V.
The LTC1872 boasts a ±2.5% output voltage accuracy and consumes only 270mA of quiescent current. For applications where efficiency is a prime consideration, the LTC1872 is configured for Burst Mode operation, which enhances efficiency at low output current.
In shutdown, the device draws a mere 8mA. The high 550kHz constant operating frequency allows the use of asmall external inductor.
The LTC1872 is available in a small footprint 6-lead SOT-23. n Lithium-Ion-Powered Applications
