42V Quad Synchronous Step-Down DC/DC Converter Delivers 93% Efficiency & Operates from 3V to 42V Inputs

Linear Technology Corporation announces the LT8602, a 42V input capable, high efficiency quad output synchronous monolithic step-down switching regulator. Its quad channel design combines two high voltage 2.5A and 1.5A channels with two lower voltage 1.8A channels to provide four independent outputs, delivering voltages as low as 0.8V. Its synchronous rectification topology delivers up to 93% efficiency while Burst Mode® operation keeps quiescent current under 30µA (all channels) in no-load standby conditions, making it ideal for always-on systems.

Atmel’s single-wire EEPROM

Inside Atmel's one-wire EEPROM 

New from Atmel is a self-powered EEPROM which has just two active pins; one for data (SI/O) and the other for earth return(GND), no connection to a supply voltage is necessary. The SI/O signal acts as both data and power line, the EEPROM harvesting power from the data signal during the high time of the protocol sequence. The memory also has a factory-assigned 64-bit unique serial number for each device and with ESD tolerance to IEC 61000-4-2, the SI/O line can be directly accessed from outside the application. 

Versatile 35VIN/35VOUT Synchronous Buck Battery Charger Controller Offers up to 20A Charge Current, Multichemistry Operation & Digital Telemetry

Linear Technology Corporation introduces the LTC4015, a highly integrated, high voltage multichemistry synchronous step-down battery charger controller with onboard telemetry functions. The device efficiently transfers power from a variety of input sources, such as wall adapters and solar panels, to a Li-Ion/Polymer, LiFePO4 or lead-acid battery stack and system load up to 35V. It provides advanced system monitoring and management functionality, including battery coulomb counting and health monitoring.

XGD10402 Series - 0.04pF, 24Vmax, 30kV, ESD Suppressors

GD Series XTREME-GUARDTM ESD Suppressors protect sensitive electronic equipment against extreme ESD conditions. This series product is specifically designed to suppress fast-rising ESD transients up to 30kV while adding virtually no capacitance to the circuit, which helps preserve signal integrity and minimize data loss for high-speed dataline applications. Its flat top surface facilitates pick-and-place assembly and enables more compact circuit board designs. It is RoHS-compliant, halogen-free, and Pb-free.
