11 / 15 page MP2110 – 3A SYNCHRONOUS BUCK CONVERTER WITH INPUT CURRENT LIMIT MP2110 Rev. 1.11 www.MonolithicPower.com 11 9/26/2014 MPS Proprietary Information. Patent Protected. Unauthorized Photocopy and Duplication Prohibited. © 2014 MPS. All Rights Reserved. Output over Voltage Clamp As the system input voltage rises up and the current limit switch’s output exceeds its OVP threshold 5.65V, the output voltage (REGIN) will be clamped to 5.65V. Current Limit Switch Output Discharge When the current limit switch’s input SYSIN is lower than 2.9V, MP2110 turns on the discharge MOSFET to discharge the REGIN capacitor storage. Discharge resistance is typical 8.5Ω and the specific discharge time depends on the capacitance between REGIN and GND. Negative Thermal Coefficient (NTC) Thermistor The MP2110 has a built-in NTC comparator that allows it to sense the external device’s temperature via the thermistor mounted near the device. It ensures a safe operating environment and prevents any smoke and fire happen due to over temperature. Connect an appropriately- valued resistor from SYSIN to the NTC-pin and connect the thermistor from the NTC-pin to AGND. The resistor divider with a dividing ratio depends on device temperature determines the voltage on the NTC-pin. Once the voltage at the NTC-pin falls to 14.5% of VSYSIN, the MP2110 output is disabled. The MP2110 restarts if the voltage rises to 27% of VSYSIN. Thermal Shutdown Thermal shutdown is implemented to prevent the chip from operating at exceedingly high temperatures. When the silicon die temperature is higher than 160°C, it shuts down the whole chip. When the temperature is lower than its lower threshold, typically 140°C, the chip is enabled again. |
