Description
The NR421A is Synchronous Rectification buck regulator ICs integrates PowerMOSFETs.
With the current mode control, low ESR capacitors such as ceramic capacitors can be used.
It has achieved a high efficiency by the synchronous rectification system.
Features
- & Benefits.
- For excellent heat dissipation, HSOP8 package with the heat-slug is adopted.
- Current mode PWM control.
- Up to 94% efficiency.
- Stable with low ESR ceramic output capacitors.
- Built-in protection function Drooping type Over Current Protection (OCP) with Auto-restart Thermal Shutdown (TSD) with Auto-restart Under Voltage Lockout(UVLO).
- By the internal Phase Compensation, external component count reduction.
- Adjustable Soft-Start with an external capacito.
