Simple switcher regulators

17th September 2014


Texas Instruments (TI) has introduced seven Simple Switcher regulators that simplify wide VIN synchronous power supply design and help engineers create energy-efficient, electromagnetic interference (EMI) compliant products. The easy-to-use LM43600/1/2/3 and LM46000/1/2 DC/DC converters feature an input voltage range of up to 60 V for high reliability in rugged systems, and 27 micro amps of standby current that minimizes power consumption at light load. The synchronous power stage architecture reduces radiated emissions for EMC compliance in a variety of industrial, automotive and communications applications. 

The LM43600, LM43601, LM43602 and LM43603 synchronous regulators support an input voltage range from 3.5 V to 36 V and generate output currents of up to 0.5 A, 1 A, 2 A and 3 A, respectively. The LM46000, LM46001 and LM46002 support an input of 3.5 V to 60 V and output currents of up to 0.5 A, 1 A and 2 A. The converters integrate compensation, control features and MOSFETS to reduce the bill of material (BOM) by up to seven components. The HTSSOP package is leveraged across the entire family, allowing pin- and footprint-compatibility, as well as scalability.

The regulators are fully supported in TI’s WEBENCH online design tool, helping designers generate, optimise and simulate a wide VIN design, and then export that design to a CAD program.
