Description

The NCP1256BSN65T1G is a highly integrated PWM current-mode controller designed by ON Semiconductor, catering to a wide range of power conversion applications. This versatile component is engineered to offer an optimal solution for off-line converters and is particularly suited for use in power supplies such as adapters, open-frame power supplies, and LCD monitors.

Key Features

  • Adjustable Switching Frequency: The NCP1256BSN65T1G offers a frequency range that can be externally adjusted up to 65 kHz, allowing designers to tailor the performance to specific application requirements.
  • Current-Mode Control: The current-mode architecture ensures fast transient response and excellent loop stability, making it an ideal choice for systems requiring precise power delivery.
  • Frequency Foldback: This feature helps reduce audible noise and electromagnetic interference (EMI) by decreasing the switching frequency under light-load conditions.
  • Built-in Protection: The device includes various protection features such as overcurrent protection (OCP), overvoltage protection (OVP), and undervoltage lockout (UVLO), enhancing system reliability and safety.
  • Soft-Start Capability: The soft-start function minimizes inrush current during startup, contributing to the longevity of the power supply components.
  • High-Voltage Startup: An integrated high-voltage startup circuit enables the device to start up directly from the rectified mains, eliminating the need for an additional standby power supply.

Applications

  • AC-DC Adapters
  • Open Frame Switching Power Supplies
  • Offline Battery Chargers
  • LED Lighting
  • Standby and Auxiliary Power Supplies

Product Specifications

The NCP1256BSN65T1G is available in a compact SOT-23-6 package, making it an excellent choice for space-constrained applications. Its robust design ensures reliable operation under a wide range of environmental conditions. The device's high level of integration reduces external component count, which helps to simplify design and reduce overall system cost.

With its combination of features, protections, and design flexibility, the NCP1256BSN65T1G from ON Semiconductor is an exceptional choice for engineers looking to enhance the performance and reliability of their power supply designs.
