N-Channel 30 V 161A (Tc) 140W (Tc) Surface Mount TO-252AA (DPAK) The IRLR7843TRPBF is an N-channel power MOSFET built on Infineon's HEXFET technology platform, originally developed by International Rectifier. It is designed as a low-voltage, high-current switching device intended for applications where minimizing conduction loss and maximizing efficiency are primary design goals. The part is particularly well suited to synchronous switching topologies, where pairs or arrays of MOSFETs alternately conduct to regulate power flow with minimal energy dissipation. This device targets high-density power conversion applications where board space is limited but current demands are substantial, such as notebook computer power delivery, point-of-load converters used in servers, and advanced telecom and datacom equipment. It is commonly found supporting synchronous buck converter stages that step down a higher input rail to a lower output voltage suitable for powering processors, memory, and other low-voltage digital logic. Its low on-resistance characteristic allows it to carry significant current while generating comparatively little resistive heating, which is essential in compact enclosures with constrained thermal budgets. The transistor is fabricated using a refined trench gate process that improves upon earlier HEXFET generations, offering reduced gate charge and lower switching losses alongside its low conduction resistance. This combination makes it effective in both the high-side and low-side positions of a synchronous switching cell, where fast, clean transitions reduce overlap losses and improve overall converter efficiency. The device also offers well-characterized avalanche energy ratings, giving designers confidence in its ruggedness when exposed to transient overvoltage events that can occur during switching, and it presents a very low gate impedance, allowing it to be driven efficiently by standard gate driver circuitry. Mechanically, the part is housed in a surface-mount power package with an exposed tab for enhanced thermal conduction to the host PCB, allowing heat generated during operation to be efficiently transferred away from the silicon die. This package style is widely used in power-dense designs where through-hole packages would be impractical. The device is supplied in a tape-and-reel format suitable for automated assembly and is compliant with RoHS material restrictions, reflecting current environmental and regulatory standards for electronic components.

The LT8364 is a current mode DC/DC converter with a 60V, 4A switch operating from a 2.8V to 60V input. With a unique single feedback pin architecture it is capable of boost, SEPIC or inverting configurations. Burst Mode operation consumes as low as 9μA quiescent current to maintain high efficiency at very low output currents, while keeping typical output ripple below 15mV. An external compensation pin allows optimization of loop bandwidth over a wide range of input and output voltages and programmable switching frequencies between 300kHz and 2MHz. A SYNC/MODE pin allows synchronization to an external clock. It can also be used to select between burst or pulse-skip modes of operation with or without Spread Spectrum Frequency Modulation for low EMI. For increased efficiency, a BIAS pin can accept a second input to supply the INTVCC regulator. Additional features include frequency foldback and programmable soft-start to control inductor current during startup. The LT8364 is available in a thermally enhanced 12-lead 4mm × 3mm DFN package or a thermally enhanced 16-lead MSOP package with four pins removed.
