MIC33030  
8MHz 400mA Internal Inductor Buck  
Regulator with HyperLight Load™  
General Description  
Features  
• 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 78% at 1mA  
• 21µA typical quiescent current  
• Up to 8MHz PWM operation in continuous mode  
• Ultra-fast transient response  
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. The tiny 2.5mm x 2.0mm MLF® package  
saves precious board space and requires only two external  
capacitors.  
• Low-voltage output ripple  
− 30mVpp ripple in HyperLight Load™ mode  
− 7mV output voltage ripple in full PWM mode  
• Fully-integrated MOSFET switches  
The MIC33030 is designed for use with tiny output  
capacitors as small as 2.2µF. This gives the MIC33030 the  
ease of use of an LDO with the efficiency of a HyperLight  
Load™ DC converter.  
• 0.01µA shutdown current  
• Thermal shutdown and current-limit protection  
The MIC33030 achieves efficiency in HyperLight Load™  
mode as high as 78% at 1mA, with a very-low quiescent  
current of 21µA. At higher loads, the MIC33030 provides a  
constant switching frequency up to 8MHz.  
• Fixed and adjustable output voltage options available  
(0.7V to 3.6V)  
• 2.5mm x 2.0mm 10-Lead MLF®  
• –40°C to +125°C junction temperature range  
The MIC33030 is available in a 10-pin 2.5mm x 2.0mm  
MLF® package with an operating junction temperature  
range of –40°C to +125°C.

• Portable media/MP3 players  
• Portable navigation devices (GPS)  
• WiFi/WiMax/WiBro modules  
• Digital Cameras  
• Wireless LAN cards  
• USB-powered devices  
• Portable applications
