供应PT4211是一款连续电感电流导通模式的降压恒流源
信息内容：PT4211是一款连续电感电流导通模式的降压恒流源，专门针对用于驱动1-3颗串联LED而设计。PT4211可接受的输入电压范围从5伏到30伏，输出电流可调至350mA。 PT4211 内置功率开关，采用高端电流采样方式，通过一个外部电阻设定LED平均电流。专用调光DIM引脚可以接受宽范围的PWM调光信号。当DIM的电压低于0.4伏时，功率开关关断,PT4211进入极低工作电流的待机状态。 PT4211采用SOT23-5封装。 关键特性 极少的外部元器件 输入电压范围从5V到30V 输出350mA电流 专用调光管脚可接受PWM调光 3%的输出电流精度 LED开路自然保护 高达93%的效率 输出可调的恒流控制方法 软过温保护尽大可能减少高温下LED闪烁 SOT23-5封装
供应PT6103 -线性锂电池充电管理芯片
信息内容：The PT6103 is a highly integrated Li-ion battery linear charging management device targeted at space limited portable applications. The PT6103 offers an integrated MOSFET and current sensor, reverse blocking protection, high accuracy current and voltage regulation, charge status indication, and charge termination in SOT23,DFN6,DFN8 or ESOP8 package. The PT6103 charges a battery in three phases: trickle charging, constant current and constant voltage. No blocking diode is required due to the internal MOSFET architecture. The thermal feedback regulates the charging current to limit the chip temperature during high power operation or high ambient temperature to maximize the charge rate without risk of overheating . The charge voltage is fixed at 4.2V, and the charge current can be programmed externally with a single resistor. The PT6103 automatically terminates the charge cycle when the charge current drops to 1/10 the programmed value after the final float voltage is reached. Once t...
