NCP1589D - Low Voltage Synchronous Buck Controller

Features

  • such as adaptive non.
  • overlap circuitry and diode emulation. It normally operates at a range of 200.
  • 500 kHz in continuous current conduction mode, which reduces with current at light load for further power saving. Protection features include programmable overcurrent protection, output overvoltage and undervoltage protection and input undervoltage lockout (UVLO). Feature.

NCP1589D Low Voltage Synchronous Buck Controller with Light Load Efficiency and Transient Enhancement The NCP1589D is a low cost PWM controller designed to operate from a 5 V or 12 V supply. This device is capable of producing an output voltage as low as 0.8 V and converting voltage from as low as 2.5 V. It is easy to operate and provides an optimal level of integration to reduce size and cost of the power supply. It operates in Ramp Pulse Modulation mode for superior load step and release response. In addition to fast transient response, it also includes a 1.5 A gate driver design and light load efficiency features such as adaptive nonāˆ’overlap circuitry and diode emulation.
