LTC3807 38V Micropower Synchronous Buck Controller with VOUT to 24V – Video Product Brief

Electronics News Updates / By Ibrar Ayyub

The LTC®3807 is a high performance step-down switching regulator DC/DC controller that drives an all N-channel synchronous power MOSFET stage. A constant frequency current mode architecture allows a phase-lockable frequency of up to 750kHz. The 50μA no-load quiescent current extends operating run time in battery-powered systems. OPTI-LOOP® compensation allows the transient response to be optimized

Two AA cell instrumentation amplifier for body networks

Electronics News Updates / By Ibrar Ayyub

The AD8237 is a micropower, zero drift, rail-to-rail input and output instrumentation amplifier. The relative match of two resistors sets any gain from 1 to 1000. The AD8237 has excellent gain accuracy performance that can be preserved at any gain with two ratio-matched resistors. The AD8237 employs the indirect current feedback architecture to achieve a
