Texas Instruments LMR10530XSD/NOPB

The LMR10530 regulator is a monolithic, high frequency, PWM step-down DC/DC converter available in a 10-pin WSON package. It contains 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 LMR10530 is easy to use. The ability to drive 3.0A loads with an internal 56 mΩ PMOS switch using state-of-the-art 0.5µm BiCMOS technology results in the best power density available. The 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 1.5MHz or 3.0MHz, allowing the use of extremely small surface mount inductors and capacitors. 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 300nA. The LMR10530 utilizes peak current-mode control and internal compensation to provide high-performance regulation over a wide range of operating conditions. Additional features include internal soft-start circuitry to reduce inrush current, cycle-by-cycle current limit, frequency foldback, thermal shutdown, and output over-voltage protection.
