2.4MHz, 3A x 2ch. Synchronous Buck Converter for POL
The NJW4110 is a synchronous 2ch. buck converter with 3A MOSFET. The switching oscillating frequency is adjustable from 100kHz to 2,4MHz. Also, it can be synchronized with external clock. The NJW4110 can be selected PFM to ensure high efficiency at light load. The NJW4110 has a single oscillator and operates an Ant-Phase switching to reduce input ripple current Each buck converters have independent enable functions, soft start functions, over current protection and power good functions. The protection functions are UVLO and thermal shutdown circuit. It is suitable for power supply circuit of SoC, DSP, DDR memory and so on that need fast transient response.
- Power supply for SoC, ASIC, DDR and the others
