BD86852MUF-C
用於相機的PMIC（電源管理IC）「BD86852MUF-C」可以為各主要製造商的CMOS感光元件的電源系統提供更好的管理功能。由於僅透過單顆IC即可進行電壓設定和時序控制，因此安裝面積可減少約41％，有助車電相機模組小型化。另外，由於電路結構可將集中在相機用PMIC上的熱量分散，因此透過抑制發熱量，達到了78.6%的高轉換效率，有助進一步降低功耗。
OVERVIEW
BD86852MUF-C is a power management IC with primary buck converter (DC/DC1), secondary buck converters (DC/DC2 and DC/DC3), external linear regulator control block and the power-on reset function for CMOS sensor and image sensing power supply. Output voltage and sequence are selectable and applicable to various image sensor power supply. This device adopts small package VQFN24FV4040 which is optimal for camera module. In addition, this device has a pin that can be programmed to turn on/off the spread spectrum providing a lower noise regulated outputs.
