NS611X, NS6110, NS6112, NS6116 NS611x 8V-30V input, 5V/2.1A&2.4A output synchronous step-down regulator
    NS611X, NS6110, NS6112, NS6116 The NS611x is A synchronous step-down power management chip that supports high voltage input, enabling 2.1A/2.4A/3A continuous current output over a wide input voltage range of 8 to 30V. By adjusting the partial voltage resistance of the FB port, a stable voltage of 1.8V to 28V can be output.
    The NS611x has excellent load adjustment and line voltage adjustment, no more than ±3% across the range. The NS611x uses the current mode loop control principle to achieve fast dynamic response.
    The NS611x operates at a switching frequency of 130kHz and has good EMI characteristics. The NS611x has built-in line voltage compensation, which can be achieved by adjusting the partial voltage resistor resistance of the FB port. The NS611x can not only realize the single-chip step-down power management solution, but also form a fast charging power management solution with the QC2.0/QC3.0 identification chip. In addition, the chip contains multiple protection functions: overtemperature protection, output short-circuit protection and input undervoltage/overvoltage protection.
    The NS611x comes in a standard SOP8 package
