The MIC33030 is a high-efficiency, 8MHz, 400mA synchronous buck regulator with an internal inductor and HyperLight Load® mode. HyperLight Load® provides very high efficiency at light loads and ultra-fast transient response that is perfectly suited for supplying processor core voltages. An additional benefit of this proprietary architecture is the very low output ripple voltage throughout the entire load range with the use of small output capacitors.

Internal inductor
Simplifies design to two external capacitors
Input voltage: 2.7V to 5.5V
Output voltage accuracy of ±2.5% over temperature
400mA output current
Efficiency up to 75% at 1mA
21μA typical quiescent current
Up to 8MHz PWM operation in continuous mode
Ultra fast transient response
Low-voltage output ripple
Thermal shutdown and current-limit protection
Fixed and adjustable output voltage options available (0.7V to 3.6V)
2.5mm x 2.0mm 10-Lead
-40°C to +125°C junction temperature range
