MP2562DS-LF-Z
Monolithic Power Systems · DC-DC Converters · SOIC-8
MP2562DS-LF-Z from Monolithic Power Systems, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | SW | output | Switch node and output of the high-side switch; a low forward drop Schottky diode to ground is required close to the SW pins, and VSW is rated from -0.3V (-5V for <10ns) to VIN +0.3V. |
| 2 | EN | input | Enable input: pulling it below the specified threshold (falling threshold 1.2V, rising 1.5V) shuts the chip down, while floating or pulling it above the threshold enables the chip. |
| 3 | COMP | output | Output of the internal error amplifier for loop frequency compensation; COMP is clamped between 0.9V and 2.0V during operation and should not be pulled up beyond 2.6V. |
| 4 | FB | input | Input to the error amplifier; the output voltage is set by a resistive divider from VOUT to GND, scaling VOUT to the internal 0.8V reference (VFB 0.776V to 0.824V). |
| 5 | GND | power_in | Ground; connect as close as possible to the output capacitor to shorten the high-current switch paths. |
| 6 | FREQ | input | Switching frequency program input; a resistor from this pin to ground sets the switching frequency up to 4MHz (for example RFREQ = 18kΩ gives 3.2 to 4.8MHz). |
| 7 | VIN | power_in | Input supply for the internal control circuitry, both BST regulators and the high-side switch, operating from 4.5V to 50V; a decoupling capacitor to ground must be placed close to this pin. |
| 8 | BST | power_out | Bootstrap positive supply for the internal floating high-side MOSFET driver; a bypass capacitor connects between BST and SW, and BST to SW is rated to 6V maximum. |
