Dual Ideal Diode & Hot Swap Controllers Save Power & Board Area
Linear Technology Corporation introduces the LTC4227, a compact, dual ideal diode with Hot Swap™ controller that provides PowerPath™ and inrush current control for redundant supplies operating from 2.9V to 18V. The LTC4227 regulates the forward voltage drop across two external N-channel MOSFETs to ensure smooth current transfer between supplies in diode-OR applications.
36V Input Dual 800mA Micropower Step-Down Regulator Has Integrated Power-On Reset & Watchdog Timer
Linear Technology Corporation announced the LT3688, a dual 800mA, 36V input step-down switching regulator with dual power-on reset and a watchdog timer. The LT3688’s 3.8V to 36V input voltage range makes it ideal for load dump and cold crank conditions commonly found in automotive applications. Its dual 1.2A internal switches deliver up to 800mA of continuous output current from each channel at output voltages as low as 0.8V.
