The PW5300 is a current mode boost DC-DC converter. Its PWM circuitry with built-in 0.2? 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 是一款完整的單節鋰電池充電器，帶電池正負極反接保護、 輸入電源正負極反接保護的芯片，兼容大小 3mA-600mA 充電電流。 PW4065 可以適合 USB 電源和適配器電源工作。由于采用了內部 PMOSFET 架構，加上防倒充電路，所以不需要外部檢測電阻器和隔離二極管。熱反饋可對充電電流進行自動調節，以便在大功率操作或高環境溫度條件下對芯片溫度加以限制。充滿電壓可分為兩檔： 4.35V、 4.2V。充電電流可通過一個電阻器進行外部設置。當電池達到預設電壓之后，充電電流降至設定值 1/10， PW4065 將自動終止充電。當輸入電壓（交流適配器或 USB 電源）被拿掉時， PW4065 自動進入一個低電流狀態，電池漏電流在 1μA 以下。 PW4065 的其他特點包括電源自適應、 欠壓閉鎖、自動再充電和一個用于指示充電狀態的引腳。PW4065 采用 SOT23-5L 封裝配合較少的外圍原件使其非常適用于便攜式產品
