GENERAL DESCRIPTION
In addition, the 100% duty cycle and HyperLight Load® (HLL) mode-of-operation delivers very-high efficiency at light loads and ultra-fast transient response which makes the MIC33163/4 perfectly suited for any space constrained application and 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. 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 soft-start to reduce inrush current, foldback current limit, power good (PG) indicator and thermal shutdown. The MIC33163/4 is available in 20-pin 2.5mm × 3.0mm × 1.1mm QFN package with an operating junction temperature range from –40°C to +125°C. Datasheets and support documentation are availab...
