DESCRIPTIONThe 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
temperature coefficient to compensate for the RDS(on)
variation of the MOSFET . This resistor-less current
protection simplifies the system design and reduces the
external parts count. The LDO controller includes
current-limit protection. Other features, such as
undervoltage lockout, power good, overvoltage,
undervoltage, and programmable short-circuit
protection promote system reliability.
