DESCRIPTIONThe TPS5124 is dual independent high efficiency
synchronous step-down controller. It supports a
low-voltage/high-current power supply applica−
tions that use either a 5-V or 12-V bus voltage.
Since both controllers of the TPS5124 operate
180 degree out-of-phase, the input current ripple
is minimized resulting in a smaller input
capacitance and reduced power supply cost.
The current protection circuit detects the
drain-to-source voltage drop across the high-side
and low-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 and built-in boost
diode simplify the system design and reduces the
external parts count. Other features such as
undervoltage lockout, overvoltage, undervoltage,
and programmable short-circuit protection
promote system reliability.
