Nisshinbo NP8700 Quad Channel Combination Regulators

Nisshinbo NP8700 Quad Channel Combination Regulators include one wide input range buck converter, two secondary converters, and one Low Dropout (LDO) using a BCD process. These regulators are operated in anti-phase operation between Ch.1 and Ch.2/3 to reduce EMI noise. The NP8700 quad-channel combination regulators expand the choices when building a power supply block suitable for various applications. These regulators feature two types of over-current protection: hiccup/foldback and latch, which can be switched depending on the application requirements. The NP8700 quad-channel combination regulators are AEC-Q100 automotive grade 1 qualified and available in a 3.4mm x 2.6mm QFN package. Typical applications include camera modules and photoelectric sensors.

Features

Including four regulators:
- Ch.1: high voltage 1.2A synchronous buck converter
- Ch.2: low voltage 1.0A synchronous buck converter
- Ch.3: selectable regulator (Low voltage 1.0A synchronous buck converter or low voltage 0.2A LDO)
- Ch.4: low voltage 0.2A LDO or low voltage Load switch (0.2A)
Wide operating input voltage range:
- 3.9V to 20V (Ch.1)
- 2.4V to 5.5V (Ch.2, Ch.3, and Ch.4)
Output voltage range:
- 2.5V to 5.5V (Ch1.)
  0.8V to 3.6V (Ch.2, Ch.3, and Ch.4)
