Future Electronics Features Micrel’s MIC33163/4 Synchronous Buck Regulators

Posted Nov 28, 2014 by futureelec
Future Electronics has announced immediate availability of the highly efficient MIC33163/4 synchronous buck regulators from Micrel.

FOR IMMEDIATE RELEASE (Press Release) Nov 28, 2014 -- Future Electronics, a global leading distributor of electronic components, offers availability of the highly efficient MIC33163/4 synchronous buck regulators from Micrel.

The MIC33163 is a highly efficient synchronous buck regulator with integrated inductor which provides the optimal trade-off between footprint and efficiency. The MIC33163/4 operates at 4MHz switching frequency and provides up to 1A output current. In addition, the 100% duty cycle and HLL mode of operation delivers very-high efficiency at light loads and ultra-fast transient response, making the MIC33163/4 ideally suited for space constrained applications and a great alternative for low dropout regulators. An additional benefit of this proprietary architecture is very low output ripple voltage throughout the entire load range with the use of small output capacitors.

The MIC33163/4 provides a small compact total solution size of 4.6mm x 7mm with very few tiny external components.

At higher loads, the MIC33163/4 provides a constant switching frequency around 4MHz while achieving peak efficiencies up to 93%. It also includes under-voltage lockout to ensure proper operation under power-sag conditions, internal softstart to reduce inrush current, fold-back current limit, power good indicator and thermal shutdown. The MIC33163/4 is available in 20-pin 2.5mm × 3.0mm x 1.1mm QFN package with an operating junction temperature range from -40°C to +125°C.
