TIDA-00388
具有出色瞬態回應的低雜訊線性穩壓器加 DC/DC 參考設計
TIDA-00388
概覽
This reference design features both a low noise LDO and a DC/DC convertor where both can source of to 3A of output current. The DC/DC design has focused on keeping transient response within 5%, a requirement when powering core voltages of digital loads. The LDO output also has good transient response and low noise (< 15 µRMS) making it ideal for powering sensitive clock circuits or digital I/O.
特點
- Dual 3A Outputs in a small solution size (~400 mm2)
- 3.3% Transient Droop @ 1.2V, 300mA to 3A, 1A/µs
- DC/DC output ripple less than 10mV peak to peak
- High LDO PSRR at switching frequencies: 54dB @ 750kHz, IOUT = 3A
- LDO output noise less than 15µV RMS, 10Hz to 100kHz
- Monotonic voltage ramps for both the 1.2V and 1.5V outputs
