SIMPLE SWITCHER® converters

SIMPLE SWITCHER synchronous DC/DC switching regulators eliminate the need for an external diode or FET, reducing solution size while improving system reliability and performance.

SIMPLE SWITCHER DC/DC regulator ICs with low standby and shutdown quiescent current are ideal for battery-operated systems or systems that spend a majority of the time in a standby state. In addition to improved performance, low quiescent current can also reduce system cost in these types of systems by eliminating the need for a low-IQ LDO in parallel to the regulator.

In contrast to all other SIMPLE SWITCHER DC/DC step-down regulators, the family of boost converters is used to increase an input voltage to a higher output voltage.

This easy-to-use family of DC/DC step-up (boost) regulator ICs can provide up to 40 V output while also reducing board space. All of these devices are available with small packaging options – like the SOT23 at less than 3 mm x 3mm - and a minimal number of required external components.

SIMPLE SWITCHER DC/DC switching regulator families can require fewer than 5 external components, making them a great choice for power engineers looking to simplify their system design and lower their BOM and solution count.

SIMPLE SWITCHER DC/DC regulator ICs provide the high efficiency demanded by today's trends of increasing power needs and shrinking board space. Even with the high voltage step-down ratios common in industrial, automotive, and communications infrastructure systems, many SIMPLE SWITCHER regulators provide greater than 90% efficiency at full load as well as high light load efficiency.

Thermal management is a major concern for any power designer, and SIMPLE SWITCHER DC/DC switching regulators are designed to provide superior thermal performance and easy implementation, with robust packaging featuring thermal resistance as low as 20° C/W.

The LMR family of SIMPLE SWITCHER DC/DC buck regulators features compact packaging, minimal BOM count, and high switching frequency to allow for the use of small surface mount inductors and chip capacitors.

SIMPLE SWITCHER buck regulators featuring low minimum on-time technology allow power supply designers to step down from high V_IN to the load voltage with high frequency operation. This eliminates the need for an intermediate voltage rail and reduces total system BOM count.

SIMPLE SWITCHER has a large portfolio of easy to use DC/DC wide VIN switching regulators qualified to the AEC-Q100 automotive stress test specification. These devices are a great fit for nominal 12 V or 24 V battery systems, with input transient protection as high as 42 V.
