Voltage Regulators
A voltage regulator is an electronic device that maintains a constant output voltage level, regardless of changes in the input voltage or load conditions. These devices are commonly used to provide a stable power supply to electronic circuits, as well as to protect them from voltage spikes and surges. There are several types of voltage regulators, including linear, switching, and pulse width modulation (PWM) regulators, each with its own set of characteristics and applications. Linear regulators, for example, are simple and efficient, but have a relatively low switching speed and can only provide a limited output current. Switching regulators, on the other hand, have higher switching speeds and can provide a higher output current, but are more complex and require additional components. In addition to their use in power supplies and voltage protection, voltage regulators are also used in a wide range of other applications, including motor control, battery charging, and instrumentation. Flux.ai has the world's largest community-driven public library of voltage regulators, with footprints, symbols, datasheets, and simulation models for a wide range of devices. Whether you're a designer, engineer, or hobbyist, you can find the resources you need to get your project up and running quickly and efficiently.
LM65645SRZTRQ1
Buck Switching Regulator IC Positive Adjustable (Fixed) 0.8V (3.3V, 5V) 1 Output 4.5A 20-WFQFN Exposed Pad The LM656x5-Q1 are a family of automotive buck converters designed for high efficiency, high-power density, and ultra-low electromagnetic interference (EMI). The converters operate over a wide input voltage range of 3V to 65V (70V transient < 100ms), reducing the need for external input surge protection. The LM656x5-Q1 comes with pin selectable fixed output voltages of 3.3V and 5V or in adjustable configuration. The low EMI operation is enabled with minimized loop inductance and optimized switch node slew rate. A pin-selectable ±5% or ±10% dual-random spread spectrum (DRSS) significantly reduces peak emissions through a combination of triangular and pseudo-random modulation while keeping output voltage ripple very low. The current-mode control architecture with a 30ns typical minimum on-time allows high conversion ratios at high frequencies coupled with a fast transient response and excellent load and line regulation.
