A New Approach to Circuit Breaker Design Using Silicon Carbide Switches - Nov 21
Mechanical circuit breakers can be low cost with minimal losses, but they operate slowly and wear out. Solid state versions overcome the problems and are becoming increasing viable as replacements at...

Regulators extend battery lifetime for energy-conscious IoT systems

The distributor offers the Recom R-78S boost switching regulators to enable designers to power devices such as microcontrollers, radio modules, or energy-conscious internet of things (IoT) systems at up to 100mA for long periods from a single 1.5V cell.

 

The 0.33W regulators ensure longer lifetime by maintaining a stable 3.3V output as the battery discharges as low as 0.65V. The wide input-voltage range enhances flexibility to use alkaline, NiCd, NiMH, zinc-carbon or lithium cells. The converters are also extremely energy efficient, says Dengrove, operating at up to 93% efficiency at full load and over 80% at lighter loads. No-load current consumption is 160μA, and can be reduced to 7μA by using the control pin.

 

The boost converters deliver the same plug-and-play convenience of the buck series, and integrate continuous short-circuit protection with auto-recovery, over-temperature protection, and under-voltage lockout to prevent deep discharge of rechargeable cells. They are specified for operation in ambient temperature range from -40 to 100°C and certified to the new EN62368-1 standard. The regulators are housed in a UL94V-0 plastic SIP4 package that measure just 11.6 x 8.5 x 10.4mm. All devices are covered by the manufacturer's three-year warranty.
