D 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 …
