NP8700 Series
Quad Channel Combination Regulator
Description
The NP8700 is quad channel combination regulator including one wide input range buck converter, two secondary synchronous buck converters and one LDO, using a BCD process. Ch.3 can be selectable to the synchronous buck converter mode or LDO mode. Ch4. can be selectable to LDO mode or load switch mode. Therefore, the NP8700 expands the choices when building power supply block suitable for various applications. The NP8700 is operated anti-phase operation between Ch.1 and Ch.2 / 3 in order to reduce EMI noise. Also, NP8700 included SSFM operation. The power on sequence can be set with just one external resistor. Therefore, flexible power on sequence configuration is available, and the power-good function's delay time can be set using an external CDELAY, eliminating the need for an additional reset IC. NP8700 has two types of over-current protection: hiccup/foldback and latch, which can be switched depending on the application requirements. The over-current protection uses a detection method that is safer and contributes to the miniaturization of inductors. Small package: 3.4mm x 2.6mm QFN is adopted suitable for small application such as camera module.。
