Data Sheets:
The MIC23451 is a high-efficiency, 3MHz, triple 2A, synchronous buck regulator with HyperLight Load® mode. HyperLight Load provides very-high efficiency at light loads and ultra-fast transient response, which is ideal for supplying processor core voltages. 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 4mm x 4mm QFN package saves board space and requires only five external components for each channel.
The MIC23451 is designed for use with a very small inductor, down to 0.47µH, and an output capacitor as small as 2.2µF that enables a total solution size that is less than 1mm height.
The MIC23451 has a very-low quiescent current of 24µA each channel and achieves as high as 81% efficiency at 1mA. At higher loads, the MIC23451 provides a constant switching frequency around 3MHz while achieving peak efficiencies up to 93%.
The MIC23451 is available in a 26-pin 4mm x 4mm QFN package with an operating junction temperature range from -40°C to +125°C.
- Input voltage: 2.7V to 5.5V
- Three independent 2A outputs
- Up to 93% peak efficiency
- 81% typical efficiency at 1mA
- Three independent Power Good Indicators
- 24µA typical quiescent current (per channel)
- 3MHz PWM operation in continuous mode
- Ultra-fast transient response
- Low voltage output ripple
- 30mVpp ripple in HyperLight Load® mode
- 5mV output voltage ripple in full PWM mode
- Fully integrated MOSFET switches
- 0.1µA shutdown current
- Thermal shutdown and current limit protection
- Output voltage as low as 1.0V
- 26-pin 4mm x 4mm QFN package
- Junction temperature range of -40°C to +125°C
