3 Description
The LM21212-1 is a monolithic synchronous point-ofload
buck regulator that is capable of delivering up to
12 A of continuous output current while producing an
output voltage down to 0.6 V with outstanding
efficiency. The device is optimized to work over an
input voltage range of 2.95 V to 5.5 V, making it
suited for a wide variety of low voltage systems. The
voltage mode control loop provides high noise
immunity, narrow duty-cycle capability and can be
compensated to be stable with any type of output
capacitance, providing maximum flexibility and ease
of use.
The LM21212-1 features internal overvoltage
protection (OVP) and overcurrent protection (OCP)
for increased system reliability. A precision enable pin
and integrated UVLO allow turnon of the device to be
tightly controlled and sequenced. Start-up inrush
currents are limited by both an internally fixed and
externally adjustable soft-start circuit. Fault detection
and supply sequencing are possible with the
integrated power good circuit.
The LM21212-1 is designed to work well in multi-rail
power supply architectures. The output voltage of the
device can be configured to track an external voltage
rail using the SS/TRK pin. The switching frequency
can be synchronized to the falling edge of a clock
between frequencies of 300 kHz to 1.5 MHz.
