NCP1522BUGEVB: 3.0 MHz, 600 mA step-down DC-DC converter evaluation board

NCP1522BUGEVB: 3.0 MHz, 600 mA Step-Down DC-DC Converter Evaluation Board

Overview

The NCP1522B step- down DC-DC converter is a monolithic integrated circuit optimized for portable applications powered from one cell Li- Ion or three cell Alkaline/NiCd/NiMH batteries. The part, available in adjustable output voltage versions ranging from 0.9 V to 3.3 V, is able to deliver up to 600 mA. It uses synchronous rectification to increase efficiency and reduce external part count. The device also has a built- in 3 MHz (nominal) oscillator which reduces component size by allowing smaller inductors and capacitors. Automatic switching PWM/PFM mode offers improved system efficiency. Additional features include integrated soft- start, cycle- by- cycle current limiting and thermal shutdown protection.

Have you ever heard of negative frequencies?
For example, the RF signal is -590M----610M. After down-conversion, it becomes a baseband signal of -10M---10M. After AD conversion, can the negative frequency here be sampled by A/DC? In other words,
