Analog Devices has introduced a step-down switching regulator that delivers up to 120mA from up to 42V, then shuts down to 2.5μA. Operating down to 3.2V (2.9V typ), the synchronous LT8604 will switch as fast at 2.2MHz and as slow as 200kHz – programmable by resistor. Efficiency can be over 90%. Topology is peak current mode, with ...
