LM21215AMH-1/NOPB General Description

LM21215A, the latest offering in synchronous buck DC-DC converters, is a game-changer in the industry. It boasts an impressive output current of up to 15A at minimum output voltages, making it a versatile choice for a wide range of low voltage systems. What sets the LM21215A apart is its voltage-mode control loop with high gain-bandwidth error amplifier that provides unparalleled noise immunity and narrow duty cycle capability. With internal overvoltage protection and cycle-by-cycle overcurrent protection, this DC-DC converter ensures increased system reliability. Additionally, the precision enable pin and integrated UVLO enable precise turn-on control and sequencing, while the internally-fixed or externally-adjustable soft-start circuit limits startup inrush currents. The integrated open-drain PGOOD indicator provides fault reporting and supply sequencing, further enhancing the LM21215A's usability. This product also includes features like auxiliary voltage rail tracking, monotonic startup into pre-biased loads, and switching frequency synchronization to an external clock signal, catering to diverse application needs. Encased in a thermally-enhanced 20-pin HTSSOP package with an exposed pad for low thermal impedance, the LM21215A signifies a new era of efficiency and reliability in DC-DC converters
