LT3437 60 V (with transients up to 80 V) 200 kHz step-down switching regulator has quiescent current under 100 µA. It operates within a VIN range of 3.3-60 V, making it suitable for load dump or cold-crank conditions common in automotive applications. Its 500 mA internal switch can deliver up to 400 mA of continuous output current at voltages as low as 1.
LT3437 60 V (with transients up to 80 V) 200 kHz step-down switching regulator has quiescent current under 100 IN range of 3.3-60 V, making it suitable for load dump or cold-crank conditions common in automotive applications. Its 500 mA internal switch can deliver up to 400 mA of continuous output current at voltages as low as 1.25 V. Burst mode operation offers ultra-low quiescent current needed for always-on operation and optimum battery life. A 3 x 3 mm DFN (or thermally enhanced TSSOP-16E) package and 200 kHz switching frequency provide a compact, thermally efficient footprint. www.linear.com Linear Technology Corp.
