LMR70503TM/NOPB
TEXAS INSTRUMENTS LMR70503TM/NOPB 直流-直流开关降压-升压稳压器, 可调, 2.8V-5.5V输入, -5.5V--900mV输出, 320mA输出, DSBGA-8
The is a SIMPLE SWITCHER® Buck-boost Converter with adjustable negative output voltage. 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 undervoltage lockout 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.
