The PW5300 is a current mode boost DC-DC converter. Its PWM circuitry with built-in 0.2Ω powerMOSFET make this regulator highly power efficient. The internal compensation network alsominimizes as much as 6 external component counts. The non-inverting input of error amplifierconnects to a 0.6V precision reference voltage and internal soft-start function can reduce the inrushcurrent. The PW5300 is available in the SOT23-6L package and provides space-saving PCB for theapplication fields

The PW4556 series of devices are highly integrated Li-Ion and Li-Pol linear chargers targetedat small capacity battery for portable applications. It is a complete constant-current/ constantvoltage linear charger. No external sense resistor is needed, and no blocking diode is required dueto the internal MOSFET architecture. It can deliver up to 300mA of charge current (using a goodthermal PCB layout) with a final float voltage accuracy of ±1%. The charge voltage is fixed at 4.2V or4.35V, and the charge current can be programmed externally with a single resistor. The chargerfunction has high accuracy current and voltage regulation loops and charge termination

The PW4554 is a cost-effective, fully integrated high input voltage single-cell Li-ion battery charger.The charger uses a CC/CV charge profile required by Li-ion battery. The charger accepts an inputvoltage up to 24V but is disabled when the input voltage exceeds the OVP threshold, typically 6.8V,to prevent excessive power dissipation. The 24V rating eliminates the over-voltage protection circuitrequired in a low input voltage charger

PW4065 是一款完整的单节锂电池充电器，带电池正负极反接保护、 输入电源正负极反接保护的芯片，兼容大小 3mA-600mA 充电电流。 PW4065 可以适合 USB 电源和适配器电源工作。由于采用了内部 PMOSFET 架构，加上防倒充电路，所以不需要外部检测电阻器和隔离二极管。热反馈可对充电电流进行自动调节，以便在大功率操作或高环境温度条件下对芯片温度加以限制。充满电压可分为两档： 4.35V、 4.2V。充电电流可通过一个电阻器进行外部设置。当电池达到预设电压之后，充电电流降至设定值 1/10， PW4065 将自动终止充电。当输入电压（交流适配器或 USB 电源）被拿掉时， PW4065 自动进入一个低电流状态，电池漏电流在 1μA 以下。 PW4065 的其他特点包括电源自适应、 欠压闭锁、自动再充电和一个用于指示充电状态的引脚。PW4065 采用 SOT23-5L 封装配合较少的外围原件使其非常适用于便携式产品
