Beschreibung

BD9B207NF-Z is one of the BD9Bx07NF-Z series of single synchronous buck DC/DC converter with built-in low on-resistance power MOSFETs. It can provide current up to 2 A. The output voltage can achieve a high accuracy due to ±1 % reference voltage. It features fast transient response due to constant on-time control system. The Forced PWM Mode control reduces the output voltage ripple in the whole load range. Power Good function makes it possible for system to control sequence. It achieves the high-power density and offer a small footprint on the PCB by employing 6 pins 1.5 mm x 1.5 mm small package.
