MIC24051  
12V, 6A High-Efficiency Buck Regulator  
®
with Hyper Speed Control  
Features  
General Description  
• Hyper Speed Control® Architecture Enables:  
The MIC24051 is a constant-frequency, synchronous  
buck regulator featuring a unique adaptive on-time  
control architecture. The MIC24051 operates over an  
input supply range of 4.5V to 19V and provides a  
regulated output of up to 6A of output current. The  
output voltage is adjustable down to 0.8V with a  
guaranteed accuracy of ±1%, and the device operates  
at a switching frequency of 600 kHz.  
- High Delta V Operation (VIN = 19V and VOUT  
= 0.8V)  
- Small Output Capacitance  
• 4.5V to 19V Voltage Input  
• 6A Output Current Capability, up to 95%  
Efficiency  
• Adjustable Output from 0.8V to 5.5V  
• ±1% Feedback Accuracy  
Microchip’s Hyper Speed Control® 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 the advantages of  
fixed-frequency operation and fast transient response  
in a single device.  
• 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  
The MIC24051 offers a full suite of protection features  
to ensure protection of the IC during fault conditions.  
These include undervoltage lockout to ensure proper  
operation under power-sag conditions, internal  
soft-start to reduce inrush current, foldback current  
limit, “hiccup mode” short-circuit protection and thermal  
shutdown. An open-drain Power Good (PG) pin is  
provided.  
• Supports Safe Start-Up into a Pre-Biased Load  
• –40°C to +125°C Junction Temperature Range  
• Available in a 28-pin 5 mm x 6 mm QFN Package  
Applications  
• Servers and Workstations  
• Routers, Switches, and Telecom Equipment  
• Base Stations  
The 6A HyperLight Load® part, MIC24052, is also  
available on Microchip’s web site.
