World's simplest buck regulator boosted to 2A
Micrel has boosted the output capability of the industry's simplest surface-mount DC/DC switching convertor to 2A while retaining the device's original SO-8 packaging.
Each bank has 4bit brightness control and each output has 10bit intensity control.
The MIC5400 incorporates a full suite of protection features including over temperature shutdown, power-on reset, open-fault protection, soft-start and watchdog.
"With this device we are addressing the specific needs of large-scale LED video displays", said Scott Brown, Linear and RF Business Unit Manager.
"We have incorporated a lot of features to ensure high performance and reliable operation".
The MIC5400 is designed for multiple devices to be daisychained together and to minimise the effects of power supply transients and EMI.
The MIC5400 incorporates an 8.3ns delay between the switching of each output, and each MIC5400 has a semi-random time delay to ensure that multiple MIC5400s within a system do not switch concurrently.
The MIC5400 is provided in wide SOIC-28 packaging and priced at $4.70 in 1k quantities.
Samples are available immediately, and production quantities are available in 8 weeks.
