Synchronous Step-Up Converter, ET8290, ETEK Microelectronics
The ET8290 is a high-efficiency, synchronous, current-mode, step-up converter with output disconnection. For ET8290, the output voltage can be programmed by IIC from 3.5V to 5V with 0.1V step. The ET8290 starts up from an input voltage as low as 1.9V, while providing inrush current limiting and output short-circuit protection. The integrated P-channel synchronous rectifier improves efficiency and eliminates the need for an external Schottky diode. This P-channel disconnects the output from the input during shutdown. The 1.0MHz switching frequency allows small external components, while the internal compensation and soft-start minimize external component count. The ET8290 provides a compact solution for a 5V output, 3.1A load requirement, using a supply voltage down to 2.8V.
