Overview
| Topology | Buck Converter |
| Input voltage | 12 V |
| Output 1 | 1.2 V / 2 A |
Description
The RT6212A is a high-efficiency, monolithic synchronous step-down DC/DC converter that can deliver up to 2Aoutput current from a 4.5V to 18V input supply. The RT6212A adopts ACOT architecture to allow the transientresponse to be improved and keep in constant frequency. Cycle-by-cycle current limit provides protection againstshorted outputs and soft-start eliminates input current surge during start-up. Fault conditions also include outputunder voltage protection, output over current protection, and thermal shutdown.
Features
- Integrated 163mΩ/86mΩ MOSFETs
- 4.5V to 18V Supply Voltage Range
- 500kHz Switching Frequency
- ACOT Control
- 0.8V±1.5% Voltage Reference
- Internal Start-Up into Pre-biased Outputs
- Compact Package : TSOT-23-6 Pin
- Over-Current Protection and Hiccup
