MIC24053
12V, 9A High-Efficiency Buck Regulator with Hyper Speed Control
Features General Description
В® Hyper Speed Control Architecture Enables:
-High Delta V Operation (VIN = 19V and VOUT
= 0.8V)
-Small Output Capacitance 4.5V to 19V Voltage Input 9A Output Current Capability, Up to 95%
Efficiency Adjustable Output from 0.8V to 5.5V ±1% Feedback Accuracy Any Capacitor Stable-Zero-to-High ESR 600 kHz Switching Frequency No External Compensation Power Good (PG) Output Foldback Current-Limit and “Hiccup Mode”
Short-Circuit Protection Supports Safe Startup into a Pre-Biased Load –40°C to +125°C Junction Temperature Range Available in 28-pin 5 mm x 6 mm QFN Package The MIC24053 is a constant-frequency, synchronous
buck regulator featuring a unique adaptive on-time
control architecture. The MIC24053 operates over an
input supply range of 4.5V to 19V and provides a
regulated output of up to 9A of output current. The
output voltage is adjustable down to 0.8V with a
guaranteed accuracy of В±1%, and the device operates
at a switching frequency of 600 kHz.
The Hyper Speed ControlВ® architecture allows for
ultra-fast transient response while reducing the output
capacitance and also makes (High VIN)/(Low VOUT)
operation possible. This adaptive tON ripple control
architecture
combines
