NCP1399AA-10pcs

Product description:
NCP1399AA 14 pin

14-pin NCP1399AA chip, suitable for power supply and hash boards, 600V driver, is a current mode resonant controller.

NCP1399AA is a high-performance current mode controller for half-bridge resonant converters. The controller implements a 600 V gate driver, simplifies the layout and reduces the number of external components. The built-in Brown-Out input function makes it easy to implement the controller in all applications. In applications that require a PFC front stage, NCP1399 has a dedicated output to drive the PFC controller. This function, together with the dedicated skip mode technology, further improves the light load efficiency of the entire application. This NCP1399 provides a series of protection functions, which can operate safely in any application.
This includes: overload protection, over-current protection against hard switching cycles, power-down detection, open-circuit detection of optocoupler, automatic no-load time adjustment, over-voltage (OVP) and over-temperature (OTP) protection.
Feature:

High frequency operation from 20 kHz to 750 kHz

Current mode control scheme

Automatic dead zone with maximum dead zone clamp

Dedicated startup sequence can realize the stability of fast resonance tank

Skip mode operation can improve light load efficiency

Non-mode operation with very low no-load power consumption

Latch or automatically restore overload protection

Latch or automatic recovery output short circuit protection

Latch input for severe fault conditions, such as OVP or OTP

Detuned switch protection

Open loop feedback protection

Precise power failure protection

PFC-level operation control according to load conditions

Starting current source with extremely low leakage current

Dynamic self-powered (DSS) operation in shutdown mode or failure mode

Pins are fixed to adjacent pins/open-circuit pins fail-safe

These are lead-free devices
