various end equipment’s power bus regulators with a
• Wide V
CC Input Voltage Range: 4.5 V to 18 V
cost effective, low component count, low standby
• Wide V
IN Input Voltage Range: 2.0 V to 18 V
current solution. The main control loop for the
TPS54325 uses the D-CAP2™ mode control which
• Output Voltage Range: 0.76 V to 5.5 V
provides a very fast transient response with no
• Highly Efficient Integrated FET’s Optimized
external components. The TPS54325 also has a
for Lower Duty Cycle Applications
proprietary circuit that enables the device to adapt to
