ON Semiconductor NCP1014AP06 Self-Supplied Monolithic Switcher for Low Standby-Power Offline SMPS

The NCP1014AP06 from ON Semiconductor offers a robust and efficient solution for power supply applications requiring low standby-power consumption. This integrated PWM controller and switching regulator is designed to simplify the creation of offline switched-mode power supplies (SMPS), particularly those found in low-power applications.

At the heart of the NCP1014AP06 lies a high-voltage Power MOSFET with a typical current limit of 100 mA, which is combined with a controller capable of delivering a fixed 65 kHz switching frequency. This integration results in a compact design that minimizes the number of external components required, thereby reducing the overall system cost and size.

The device features ON Semiconductor's proprietary Auto-Recovery Internal Fixed Latch Off Timer, which enhances the safety of the power supply by ensuring that the device automatically recovers from fault conditions such as overvoltage, undervoltage, or overload. This self-supplied monolithic switcher eliminates the need for an auxiliary bias winding and associated circuitry in many applications, further simplifying design and reducing component count.

In addition, the NCP1014AP06 integrates a frequency jittering sequence that helps to reduce electromagnetic interference (EMI), a critical consideration in modern electronic designs. This feature allows for the use of smaller, less expensive input filters while still complying with stringent EMI regulations.

With its built-in brown-out protection, the device ensures reliable operation under conditions of fluctuating input voltage, which is particularly important for applications that must remain functional during power anomalies. The NCP1014AP06 also includes a dynamic self-supply arrangement, eliminating the need for an auxiliary winding under no-load conditions.

Overall, the NCP1014AP06 from ON Semiconductor is a versatile and cost-effective choice for designers looking to implement an offline SMPS with low standby power consumption. Its integrated features and self-contained design make it an excellent choice for a wide range of applications, including consumer electronics, home appliances, and standby power systems.
