说明
- TIDA-00379, 110-VAC to 5-VDC @ 30-mA Non-Isolated Power Supply Reference Design. The 110-VAC to 5-VDC @ 30-mA Non-Isolated Power Supply Design uses a low-power, low-cost, off-line buck converter and a low-noise, low-dropout voltage regulator to generate a non-isolated 5V/30mA output directly from a 110-VAC line input with under 10-mV output ripple across no-load and full-load conditions. Off-line converters are powered directly from the AC line by using a rectifier and capacitive filter and do not require a large 60-Hz transformer, thereby eliminating the heaviest and costliest component of a typical transformer-based power supply
