Linear Technology Corporation announces the LT8602, a 42V input capable, high efficiency quad output synchronous monolithic step-down switching regulator. Its quad channel design combines two high voltages 2.5A and 1.5A channels with two lower voltages 1.8A channels to provide four independent outputs, delivering voltages as low as 0.8V. Its synchronous rectification topology delivers up to 93% efficiency while Burst Mode operation keeps quiescent current under 30µA (all channels) in no-load standby conditions, making it ideal for always-on systems. For noise-sensitive applications, the LT8602 utilizes its pulse-skipping mode to minimize switching noise and meet the CISPR25, Class 5 EMI requirements.

Switching frequency can be programmed from 250kHz to 2.2MHz and is synchronizable throughout this range. The LT8602's 60ns minimum on-time enables 16VIN to 0.8VOUT step-down conversions while switching at 2MHz, enabling designers to avoid critical noise-sensitive frequency bands such as AM radio, while using a very compact solution footprint. Its 3V to 42V input voltage range makes it ideal for automotive applications that must regulate through cold-crank and stop-start scenarios with minimum input voltages as low as 3V and load dump transients in excess of 40V.
