Inside the 74181 ALU chip: die photos and reverse engineering
https://www.electronics-lab.com/inside-74181-alu-chip-die-photos-reverse-engineering/
A detailed die photos and reverse engineering of the 74181 ALU chip by Ken Shirriff: What’s inside a TTL chip? To find out, I opened up a 74181 ALU chip, took high-resolution die photos, and reverse-engineered the chip.1 Inside I found several types of gates, implemented with interesting circuitry and unusual transistors. The 74181 was a […]
Multiphase, 60V synchronous boost controller peaks at 97%
https://www.electronics-lab.com/multiphase-60v-synchronous-boost-controller-peaks-97/
LTC3897 is a multiphase synchronous boost DC/DC controller with input surge stopper and ideal-diode controller. The boost controller drives two N-channel power MOSFET stages out-of-phase to reduce input and output capacitor requirements, enabling the use of smaller inductors versus the single-phase equivalent. By Graham Prophet @ edn-europe.com: Synchronous rectification increases efficiency, reduces power loss and […]
Protect your boost converter
https://www.electronics-lab.com/protect-boost-converter/
T A Babu @ edn.com discuss about a protection circuit for boost converters. Boost converters are particularly susceptible to output shorts as there is a DC path from input to output. Usually a fuse, resettable or non-resettable, protects the system, but it is not always accurate or fast enough. Protect your boost converter – [Link]
