Product Introduction

Overview

The NCP3135MNTXG from onsemi is a fully integrated synchronous buck converter designed for 3.3 V and 5 V step-down applications. This device is capable of providing up to 5 A of continuous output current and 6 A of instantaneous load current. It features high efficiency in both continuous conduction mode (CCM) and discontinuous conduction mode (DCM), along with a high operation frequency of 1.1 MHz. The NCP3135MNTXG supports MLCC output capacitors and has a small footprint, packaged in a 3 mm x 3 mm, 16-pin QFN package.

Q & A

  1. What is the input voltage range of the NCP3135MNTXG?

    The input voltage range is from 2.9 V to 5.5 V.

  2. What is the maximum continuous output current of the NCP3135MNTXG?

    The maximum continuous output current is up to 5 A.

  3. What is the operation frequency of the NCP3135MNTXG?

    The operation frequency is 1.1 MHz.

  4. What types of protection does the NCP3135MNTXG offer?

    The device offers over-voltage, under-voltage, over-current protection, and over-temperature protection.

  5. Does the NCP3135MNTXG support pre-bias start-up?
  6. What is the package type of the NCP3135MNTXG?

    The package type is QFN-16 (3 mm x 3 mm).

  7. What are the operation modes of the NCP3135MNTXG?

    The device operates in either Forced Continuous Conduction Mode (FCCM) or Automatic CCM/DCM mode.

  8. How does the automatic power-saving mode work in the NCP3135MNTXG?

    In Automatic CCM/DCM mode, when the load current decreases, the converter enters power-saving mode, reducing switching frequency and minimizing quiescent current.

  9. Does the NCP3135MNTXG have a power good indicator?
  10. What is the typical soft-start time of the NCP3135MNTXG?

    The typical soft-start time is 1 ms.
