PRODUCTION DATA.
The LMR10510 is a constant frequency PWM buck regulator IC that delivers a 1-A load current. The regulator has a preset switching frequency of 1.6 MHz or 3 MHz. This high frequency allows the LMR10510 to operate with small surface mount capacitors and inductors, resulting in a DC/DC converter that requires a minimum amount of board space. 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 LMR10510 utilizes 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, pulse-by-pulse current limit, thermal shutdown, and output overvoltage protection.
