WebSep 20, 2005 · Linear regulators, among other things, are tasked with shielding sensitive analog blocks from noise in the supplies, making wide-spectrum power supply ripple rejection (PSRR) a vital specification parameter. In broad terms, the function of the regulator is to generate an independent supply voltage through a series-shunt feedback …
WebCharge-pump converters provide the smallest and lowest cost solution as they rely only on small capacitors for voltage conversion. However, charge-pump converters are only efficient when generating discrete multiples of their input voltages (e.g., 1.5x, 2x). Consequently, inductor-based converters are generally used in the LED series method. WebMar 9, 2024 · Note that switching loss is proportional to switching frequency. Higher frequency means more current and voltage overlaps and more parasitic capacitor charges and discharges per unit time. This is the main reason that lower frequency circuits are more efficient.
