DESCRIPTION
The TPS5130 is composed of three independent
synchronous buck regulator controllers (SBRC) and
one low drop-out (LDO) regulator controller. On-chip
high-side and low-side synchronous rectifier drivers are
integrated
to
drive
less
expensive
N-channel
MOSFETs. The LDO controller can also drive an
external N-channel MOSFET. Since the input current
ripple is minimized by operating 180 degree out of
phase, it allows a smaller input capacitance resulting in
reduced power supply cost. The SBRC of the TPS5130
automatically adjusts from PWM mode to SKIP mode
to maintain high efficiency under light load conditions.
Resistor-less current protection for the synchronous
buck controller and the fixed high-side driver voltage
simplifies the system design and reduces the external
parts count. The LDO controller has a current limit
protection and overshoot protection to suppress output
voltage hump at load transient. To further extend
battery life, the TPS5130 features dead-time control
and very low quiescent current.
