The LTC1872B is a constant frequency current mode step-up DC/DC controller providing excellent AC and DC load and line regulation. The device incorporates an accurate undervoltage lockout feature that shuts down the LTC1872B when the input voltage falls below 2.0V.
The LTC1872B provides a ±2.5% output voltage accuracy and consumes only 270µA of quiescent current. In shutdown, the device draws a mere 8µA.
High constant operating frequency of 550kHz allows the use of a small external inductor. The constant frequency operation is maintained down to very light loads, resulting in less low frequency noise generation over a wide load current range.
The LTC1872B is available in a 6-lead low profile (1mm) ThinSOT package. For a Burst Mode operation enabled version of the LTC1872B, please refer to the LTC1872 data sheet.
