Product Introduction

Product Details:

ADP2105/ADP2106/ADP2107均为低静态电流、同步、Step-down DC-DC converters，采用4 mm × 4 mm、紧凑型LFCSP_VQ封装。对于中高负载电流，这些器件采用电流模式、恒频脉冲宽度调制(PWM)控制方案，以获得出色的稳定性和瞬态响应性能。在便携式应用中，为确保电池使用寿命最长，上述器件在低负载情况下采用脉冲频率调制(PFM)控制方案，通过降低开关频率实现省电。

ADP2105/ADP2106/ADP2107 operate from 2.7 V to 5.5 V input voltages and can be powered by a single Li+/Li− polymer battery, multiple alkaline/NiMH batteries, PCMCIA, and other standard power supplies. The output voltage of the ADP2105/ADP2106/ADP2107-ADJ can be adjusted from 0.8 V to the input voltage, while the ADP2105/ADP2106/ADP2107-xx offers preset output voltage options: 3.3 V, 1.8 V, 1.5 V, and 1.2 V. Each model is available with three maximum current levels: 1 A (ADP2105), 1.5 A (ADP2106), and 2 A (ADP2107). To minimize the number of external devices and improve power efficiency, these devices integrate a power switch and a synchronous rectifier. During logic-controlled shutdown, the input is disconnected from the output and less than 0.1 μA is drawn from the input source. Other important features include: undervoltage latching to prevent deep battery discharge; and programmable soft-start to limit inrush current at start-up.
