BD9016KV-M数据手册集成电路（IC）的PMIC-稳压器-DCDC开关式控制器规格书PDF

描述 Description

BD9016KV-M是可在宽输入范围使用的双输出同步整流开关控制器。可通过同步整流方式实现高效率，有助于所有电子设备的环保设计（低功耗化）。各输出具有EN端子、软启动功能、POWER GOOD功能，可独立控制上升沿／下降沿。此外，内置PLL电路，可与250kHz to 600kHz的外部时钟同步。

特性 Features

• N channel MOSFET direct drive
• Synchronous rectification for increased efficiency
• Acceptable Low ESR ceramic capacitor at output
• Integrated PLL circuit for external synchronization; 250kHz to 600kHz
• Current mode control
• High side MOSFET current sensing
• Pre-bias functionality
• Independent ON/OFF control for all channels
• At Max Duty the oscillation frequency is slowed down to 1/5, reducing the input/output voltage difference.
• Low voltage and over voltage detection circuit at all outputs
When the over voltage is detected, the L-side FET is OFF (BD9015KV-M). The L-side FET is ON (BD9016KV-M).
Low side FET is ON (BD9016KV-M)
• Power good indicator pin (PGOOD)
• Integrated overcurrent protection with self recovery.
