7V to 5.
5V Input Voltage • Adjustable Output Voltage (Down to 1.
0V) • Two Independent 2A Outputs • Up to 94% Peak Efficiency • 83% Typical Efficiency at 1 mA • Two Independent Power Good Indicators • Independent Programmable Soft-Start • 45 µA Typical Quiescent Current • 3 MHz PWM Operation in Continuous Conduction Mode • Ultra-Fast Transient Response • Fully Integrated MOSFET Switches • Output Pre-Bias Safe • 0.
1 µA Shutdown Current • Thermal-Shutdown and Current-Limit Protection • 20-Pin 3 mm x 4 mm QFN Package • Internal 225Ω Pull-Down Circuit on Output (MIC23159) • –40°C to +125°C Junction Temperature Range Applications • Solid State Drives (SSD) • Smartphones • Tablet PCs • Mobile Handsets • Portable Devices (PMP, PND, UMPC, GPS) • WiFi/WiMax/WiBro Applications General Description The MIC23158/9 is a high efficiency, 3 MHz, dual, 2A synchronous buck regulator with HyperLight Load® mode, power good output indicator, and programmable soft start.
The MIC23159 also provides an auto-discharge feature that switches in a 225Ω pull-down circuit on its output to discharge the output capacitor when disabled.
HyperLight Load provides very high efficiency at light loads and ultra-fast transient response which makes the MIC23158/9 perfectly suited 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 20-pin 3 mm x 4 mm QFN package saves precious board space and requires seven external components for each channel.
The MIC23158/9 is designed for use with a very small inductor, down to 0.
47 µH, and an output capacitor as small as 2.
2 µF that enables a total solution size, less than 1 mm in height.
The MIC23158/9 has a very low quiescent current of 45 µA and achieves a peak efficiency of 94% in continuous conduction mode.
