Beschreibung
- High-Performance Synchronous Buck EVM Using the TPS51220. TPS51220 is a dual peak-current mode, synchronous step-down controller with three low-dropout (LDO) regulators. It is optimized for 5V/3.3V notebook system power supplies. A 99% duty cycle operation enables designers to complete Li-ion battery applications from 2-cells to 4-cells cost effectively. The TPS51220 supports high-efficiency, fast transient response and 99% duty cycle operation. DCR current sensing provides lossless current sensing and free MOSFET selection, resistor sensing supports accurate current-sensing operation. It supports supply input voltages ranging from 4.5V to 30V and output voltages from 1V to 12V. High-current, 5V at 100am, 3.3V at 10am, on-board linear regulators have glitch-free switchover function to SMPS, and the 2V reference has a 100mA capability
