PAM2306屬于集成電路（IC）的穩(wěn)壓器-DC-DC開關(guān)穩(wěn)壓器。由龍鼎微電子（上海）有限公司制造生產(chǎn)的PAM2306穩(wěn)壓器 - DC-DC 開關(guān)穩(wěn)壓器DC-DC 開關(guān)穩(wěn)壓器 PMIC（電源管理集成電路）產(chǎn)品族中的產(chǎn)品是元器件級設(shè)備，用于需要穩(wěn)定 DC 輸入電壓和/或?qū)⑵滢D(zhuǎn)換為不同幅度的輸出電壓的應(yīng)用。這些器件與稱為“控制器”PMIC 的類似產(chǎn)品的區(qū)別在于集成了主開關(guān)元件，設(shè)備提供的電力會通過該元件。

General Description

The PAM2306 is a dual step-down current-mode, DC-DC converter. At heavy load, the constant-frequency PWM control performs excellent stability and transient response. To ensure the longest battery life in portable applications, the PAM2306 provides a power-saving PulseSkipping Modulation (PSM) mode to reduce quiescent current under light load operation.
