ON Semiconductor NCP1014AP065 Self-Supplied Monolithic Switcher for Low Standby-Power Offline SMPS

The NCP1014AP065 from ON Semiconductor is a highly integrated power switching regulator that offers a compact and efficient solution for low-power offline switched-mode power supplies (SMPS). This versatile component integrates a fixed-frequency current-mode controller with a 700 V MOSFET, making it an ideal choice for a wide range of power applications.

Designed with energy efficiency in mind, the NCP1014AP065 features a no-load power consumption of typically only 25 mW, which helps reduce standby power requirements in consumer electronics and other applications. The device operates at a fixed 65 kHz switching frequency, which allows for a good balance between efficiency and manageable EMI, making it easier to meet regulatory requirements.

The NCP1014AP065 offers various protection features to ensure reliable operation and extend the life of the power supply. These include an adjustable over-power protection to prevent stress on the MOSFET, and a brown-out detection that safeguards the device under low input voltage conditions. Additionally, the built-in frequency jittering helps to further minimize EMI emissions.

This switcher also includes an on-chip 25 mA peak startup current source, which provides quick and efficient startup without the need for an external resistor. After the startup phase, the NCP1014AP065 transitions to a low operating current mode, which contributes to its overall low power consumption.

The NCP1014AP065 is offered in a PDIP-7 package, which is not only easy to handle during the manufacturing process but also provides adequate thermal performance for most applications. This makes the NCP1014AP065 a practical choice for a variety of power conversion applications, including auxiliary power supplies, battery chargers, standby power supplies for TVs and monitors, and other small household appliances.

With its combination of energy-saving features, robust protection mechanisms, and compact form factor, the NCP1014AP065 from ON Semiconductor is a reliable and efficient solution for designers looking to optimize their power supply designs for both performance and cost.
