| Description | The SY21282 high efficiency synchronous step-up regulator operates using adaptive constant off-time and current mode control, and supports a wide input voltage range from 3V to 9V. It integrates switches with low RDS(ON) to minimize conduction loss. The SY21282 features cycle-by-cycle peak current limit, output short-circuit protection, and true shutdown. It. |
| Features |
cycle-by-cycle peak current limit, output short-circuit protection, and true shutdown. It also provides enable control and power-good indicator for system power sequencing. The 1MHz pseudo-constant frequency reduces the output voltage ripple and permits smaller external capacitors and inductor.
The SY21282 is available in a compact QFN3×316 package.
Features
● 3V to 9V Input Voltage Range ● 6A (Min.) Main MOSFET Current Limit ● 7 µA Shutdown Current (Max.) ● 600 µA Quiescent Current (Typ.) ● Programmable Output Current Limit ● Low RDS(ON) for Internal N-Channel MOSFET: 80mΩ Main, 40mΩ Rectifi. |
