Product Introduction

Overview

The NCP13992AEDR2G, produced by onsemi, is a high-performance current mode controller designed for half-bridge resonant converters. This controller integrates 600 V gate drivers, simplifying the layout and reducing the external component count. It features a suite of protection mechanisms, including overload protection, over-current protection, brown-out detection, open optocoupler detection, automatic dead-time adjustment, over-voltage (OVP), and over-temperature (OTP) protections. The NCP13992AEDR2G also includes advanced features such as quiet skip mode for minimizing transformer acoustic noise and light load operation mode for improved efficiency.

Q & A

  1. What is the operating frequency range of the NCP13992AEDR2G? The operating frequency range is from 20 kHz to 750 kHz.
  2. What is the VCC turn-on threshold for the NCP13992AEDR2G? The VCC turn-on threshold is between 11.5 V and 15.8 V.
  3. What are the key protection features of the NCP13992AEDR2G? The key protection features include overload protection, over-current protection, brown-out detection, open optocoupler detection, automatic dead-time adjustment, over-voltage (OVP), and over-temperature (OTP) protections.
  4. How does the quiet skip mode operate in the NCP13992AEDR2G? The quiet skip mode minimizes transformer acoustic noise by adjusting the skip threshold via a resistor connected to ground.
  5. What is the purpose of the PFC mode in the NCP13992AEDR2G? The PFC mode provides supply voltage for the PFC front stage controller and/or enables the Vbulk sensing network HV switch according to load conditions.
  6. What are the typical applications of the NCP13992AEDR2G? Typical applications include adapters and offline battery chargers, flat panel display power converters, computing power supplies, and industrial and medical power sources.
  7. How does the brown-out protection work in the NCP13992AEDR2G? The brown-out protection turns off the device when the bulk voltage falls below a specified threshold (0.965 V to 1.035 V) and includes hysteresis to prevent oscillations.
  8. What is the maximum operating temperature for the NCP13992AEDR2G? The maximum operating temperature is up to 125°C.
  9. Does the NCP13992AEDR2G support dynamic self-supply operation? Yes, it supports dynamic self-supply (DSS) operation in off-mode or fault modes.
  10. Is the NCP13992AEDR2G a Pb-free device? Yes, the NCP13992AEDR2G is a Pb-free device.
  11. How does the startup current source function in the NCP13992AEDR2G? The startup current source has an extremely low leakage current and is used for startup and dynamic self-supply functions.
