DESCRIPTION

Switching Mode Step-Down dc-to-dc  
Controller With Fast LDO Controller  
The TPS5110 provides one PWM-mode synchronous  
buck regulator controller (SBRC) and one low drop-out  
(LDO) regulator controller. The TPS5110 supports a  
low-voltage/high-current power supply for I/O and other  
peripherals in modern digital systems. The SBRC of the  
TPS5110 automatically adjusts from PWM mode to  
SKIP mode to maintain high efficiency under all load  
conditions. The LDO controller drives an external  
N-channel power MOSFET that realizes fast response  
and ultra-low dropout voltage. A unique overshoot  
protection circuit prevents a voltage hump at fast load  
decreasing transients. The current protection circuit for  
SBRC detects the drain-to-source voltage drop across  
the low-side and high-side power MOSFET while it is  
conducting. Also, the current protection circuit has a
