产品信息
芯片。工作电压 2V-5V ,以 BTL 桥连接的方式,在 5V
电源电压下,可以给3Ω负载提供 THD 小于 10% 、平均
为 3.0W 的输出功率。在关闭模式下,电流典型值小于
0.5uA 。
YX8002D 是为提供大功率、高保真音频输出而专
门设计的,它仅仅需要少量的外围元器件,并且能工
作在低电压条件下 (2V-5V)。YX8002D 不需要耦合电
容,自举电容或者缓冲网络,所以非常适用于小音量
Description
The FP6291 is a current-mode boost DC/DC converter with a build-in 16V, 2.5A, 0.18Ω internal power MOSFET to provide
this regulator highly power efficient. The FP6291 operates at 1MHz allowing for easy filtering and low noise. Internal
compensation makes the user to set system easily, which allows the use of small, low-ESR ceramic output capacitors.
Fault protection includes over-current latch off, input UVLO and thermal shutdown. This device uses current mode control
scheme that provides fast transient response. In shutdown mode, the supply current is less than 1uA. The FP6291 is available
in a SOT23-6L package, provides a very compact system and low cost solution.
