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 LMR10520 is easy to use.
The ability to drive 2-A loads with an internal 150-mΩ PMOS switch results in the best power density available.
The world-class control circuitry allows ontimes as low as 30 ns, thus supporting exceptionally high frequency conversion over the entire 3-V to 5.
5V input operating range down to the minimum output voltage of 0.
6 V.
The LMR10520 is internally compensated, so it is simple to use and requires few external components.
Even though the operating frequency is high, efficiencies up to 93% are easy to achieve.
External shutdown is included, featuring an ultra-low stand-by current of 30 nA.
The LMR10520 uses current-mode control and internal compensation to provide high-performance regulation over a wide range of operating conditions.
