The LTC3672B-1 is a triple power supply composed of a 400mA synchronous buck regulator and two 150mA low dropout linear regulators (LDOs), where one of the LDOs can be powered from the buck output to improve efficiency. Constant-frequency 2.25MHz operation is maintained down to very light loads. The input supply range of 2.9V to 5.5V is especially well-suited for single-cell Lithium-Ion and Lithium-Polymer applications, and for powering low voltage ASICs from 3.3V or 5V rails.
The LTC3672B-1 regulates 1.8V at the buck output, 1.2V at the LDO1 output, and 2.8V at the LDO2 output. External component count is minimal—all that is needed is a single inductor, an input capacitor, and output capacitors for each of the three outputs. Control loop compensation is internal to the LTC3672B-1.
The LTC3672B-1 is available in a 2mm x 2mm x 0.75mm 8-Lead DFN package.
| Buck Vout | LDO 1 | LDO 2 | |
| LTC3672B-1 | 1.8V | 1.2V | 2.8V |
| LTC3672B-2 | 1.2V | 2.8V | 1.8V |
