5A Load - Step-Down DC-DC Regulator General Description The LM2831 regulator is a monolithic, high frequency, PWM step-down DC/DC converter in a 5 pin SOT23 and a 6 Pin LLP package.
It provides all the active functions to provide local DC/DC conversion with fast transient response and accurate regulation in the smallest possible PCB area.
With a minimum of external components, the LM2831 is easy to use.
The ability to drive 1.
5A loads with an internal 130 mΩ PMOS switch using state-of-the-art 0.
5 µm BiCMOS technology results in the best power density available.
The worldclass control circuitry allows on-times as low as 30ns, thus supporting exceptionally high frequency conversion over the entire 3V to 5.
5V input operating range down to the minimum output voltage of 0.
6V.
Switching frequency is internally set to 550 kHz, 1.
