RT9232B应用电路及参数
rt9232b应用电路及参数
the rt9232b is a single-phase synchronous buck pwm dc-dc converter controller designed to drive two n- mosfets. it provides a highly accurate, programmable output voltage precisely regulated to low voltage requirement with an internal 0.8v ± 1% reference.
the rt9232b uses an external compensated, single feedback loop voltage mode pwm control for fast transient response. an oscillator with programmable frequency (50khz to 800khz) reduces the external inductor and capacitor component size for saving pcb board area.
the rt9232b provides fast transient response to satisfy high current output applications (up to 25a) while minimizing external components. it is suitable for high-performance graphic processors, ddr and vtt power.
the rt9232b integrates complete protect functions such as soft start, output enable, uvlo(under-voltage lockout) and ocp into a small 14-pin package.
