Low IQ

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.

Step-up (boost)

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.

High efficiency

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.
