Capacitors
A capacitor is a passive electronic component that stores electrical charge and is commonly used to store energy in a circuit. Capacitors are used in a wide range of applications including power supply filtering, signal coupling, and decoupling, noise suppression, and voltage dividing. One of the main use cases of capacitors is to smooth out fluctuations in a direct current (DC) power supply by acting as a temporary reservoir of electrical charge. Capacitors can also be used to block the flow of direct current while allowing alternating current to pass, making them useful for signal coupling and decoupling in audio and radio frequency circuits. Flux.ai is the world's largest community-driven public library of capacitors, offering footprints, symbols, datasheets, and simulation models for a wide range of capacitor types. Whether you're an engineer looking for detailed technical information or a maker in need of resources for your latest project, Flux.ai has you covered.
TPS259814ARPWR
Electronic Fuse Regulator High-Side 10A 10-VQFN-HR (2x2) The TPS25981xx family of eFuses is a highly integrated circuit protection and power management solution in a small package. The devices provide multiple protection modes using very few external components and are a robust defense against overloads, short circuits, voltage surges and excessive inrush current. Output slew rate and inrush current can be adjusted using a single external capacitor. Loads are protected from input overvoltage conditions by cutting off the output if input exceeds an adjustable overvoltage threshold. The devices respond to output overload by actively limiting the current (during startup) or breaking the circuit (during steady-state). The overcurrent protection threshold as well as the transient overcurrent blanking timer are useradjustable. The current limit control pin also functions as an analog load current monitor. The devices are available in a 2-mm × 2-mm, 10- pin HotRod™ QFN package for improved thermal performance and reduced system footprint. The devices are characterized for operation over a junction temperature range of –40°C to +125°C. • Wide operating input voltage range: 2.7 V to 16 V – 20-V absolute maximum • Integrated FET with low on-resistance: RON = 6 mΩ (typ.) • Fast overvoltage protection – Adjustable overvoltage lockout (OVLO) with 1.2-μs (typ.) response time • Overcurrent protection with load current monitor output (ILM) – Circuit-breaker response – Adjustable threshold (ILIM) 1.5 A – 11 A • ±10% accuracy for ILIM > 5 A – Adjustable transient blanking timer (ITIMER) to allow peak currents up to 2 × ILIM – Output load current monitor accuracy: ±10% (IOUT ≥ 3 A) • Fast-trip response for short-circuit protection – 640-ns (typ.) response time – Adjustable (2 × ILIM) and fixed thresholds • Active high enable input with adjustable undervoltage lockout threshold (UVLO) • Active low enable input with adjustable undervoltage lockout threshold (OVLO) • Adjustable output slew rate control (dVdt) • Option to drive external FET for reverse current blocking in disabled/OFF state • Overtemperature protection • Quick Output Discharge • Digital outputs – Power Good (PG) and fault indication (FLT) • UL 2367 recognition (pending) • IEC 62368 CB certification (pending) • Small footprint: QFN 2-mm × 2-mm, 0.45-mm pitch #CommonPartsLibrary #IntegratedCircuit #PowerManagement

Buck Switching Regulator IC Adjustable 1 Output 1000mA SOT-23-6 The LGS5145 is a step-down DC/DC regulator with internal switching, featuring SKIP control mode, which combines low quiescent current with high switching frequency to achieve high efficiency over a wide range of load currents. The SKIP mode uses a short “burst” cycle to switch the inductor current through the internal power MOSFETs, followed by a sleep cycle in which the power switch is turned off and the load current is supplied by the output capacitor. At light loads, the burst cycle is a fraction of the total cycle time, minimizing the average supply current and greatly improving efficiency at light loads. The LGS5145 has a wide input voltage range of 4.5V55V, minimizing the need for external surge suppression components.The LGS5145 features an integrated low resistance 0.6Ω high-side power MOSFET that provides at least 1A of output current capability with excellent load and line transient response.
