NR885E

3A, 18V, 350kHz , Synchronous Buck Regulator NR885E General Descriptions The NR885E is synchronous buck regulator ICs integrates High-side and Low-side power MOSFETs. With the current mode control, ultra low ESR capacitors such as ceramic capacitors can be used. The ICs have protection functions such as Over-Current Protection (OCP), Under-Voltage Lockout (UVLO) and Thermal Shutdown (TSD). An adjustable Soft-Start by an external capacitor prevents the excessive inrush current at turn-on the regulator. The ICs integrate phase compensation circuit which reduces the number of external components and simplifies the design of customer application. The ON/OFF pin (EN Pin) turns the regulator on or off and helps to achieve low power consumption requirements. The NR885E is available in an 8-pin SOIC package with an exposed thermal pad on the back side.
