LMR70503中文资料2.8V 至 5.5V、300mA 降压/升压负输出稳压器数据手册TI规格书

描述 Description

The LMR70503 is a buck-boost converter with adjustable negative output voltage in a tiny 8-bump thin DSBGA package. Its unique control method is designed to provide fast transient response, low output noise, high efficiency, and tight regulation in the smallest possible PCB area. The LMR70503 has built in soft start, peak current limit, minimum switching frequency, and Under Voltage Lock Out (UVLO), with no external compensation required. For ease of use, the Enable pin is referred to the IC ground, instead of the lowest potential of the IC: the negative output voltage.
