The NCP1399ACDR2G from ON Semiconductor is a high-performance current mode controller specifically designed for half-bridge resonant converters. This device integrates 600V gate drivers, simplifying circuit design and reducing the need for external components. It supports high-frequency operation ranging from 20 kHz up to 750 kHz.
The controller features a robust suite of protection mechanisms, including overload protection, over-current protection, brown-out detection, open optocoupler detection, automatic dead-time adjustment, overvoltage (OVP), and overtemperature (OTP) protections, ensuring safe operation across various applications. It also incorporates features like skip mode operation for improved light load efficiency and off-mode operation for extremely low no-load consumption.
Packaged in a 16-SOIC format, the NCP1399ACDR2G is suitable for surface mount applications. Its typical applications include adapters, offline battery chargers, flat panel display power converters, computing power supplies, and industrial and medical power sources. The device operates within a voltage range of 9.5V to 20V and has a duty cycle of 50%.
This controller is designed for isolated power supply topologies and offers features like precise brown-out protection and PFC stage operation control according to load conditions. The integrated startup current source has extremely low leakage current, and it supports Dynamic Self-Supply (DSS) operation in off-mode or fault modes.
