Its ratiometric topology means the output voltage tracks the input as a fixed multiple or inversion — useful when you need a negative rail or a doubled voltage from a single low-voltage supply without a magnetic inductor. ## Switching frequency and output configuration The internal oscillator runs at either 125kHz or 250kHz, selectable via a logic pin — the higher frequency shrinks the external capacitor size at the cost of slightly higher switching losses. Output is fixed-configuration (positive or negative) with no synchronous rectifier, so the efficiency curve peaks in the middle of the load range and drops at very light loads. ## Package and board-fit: 8-SOIC Housed in an 8-SOIC package (0.154\" width, 3.90mm body), the MAX1680ESA+T uses a standard footprint that places cleanly on a two-layer board without via-in-pad.","metaTitle":"MAX1680ESA+T Analog Devices Charge Pump, 125mA, 8-SOIC","metaDescription":"MAX1680ESA+T ratiometric charge pump from Analog Devices. 125mA output, 2V-5.5V input, 8-SOIC.
