LTC4380 Overvoltage Protection
https://www.electronics-lab.com/ltc4380-overvoltage-protection/
Thomas Scherer @ elektormagazine.com writes: When it comes to protecting sensitive circuitry from potentially damaging over-voltage spikes and supply surges we usually resort to networks of coils, capacitors, resistors and suppression diodes to iron out the transients. The LTC4380 low quiescent current surge stopper IC from Linear Technology goes about it in a different way; […]

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]
