BLI9184
BLI9184 is 3.0-A Synchronous Step-Down Converter manufactured by SHANGHAI BELLING.
Features 3.0-A Output Current High Efficient Integrated FETs Optimized for portable application: 85mΩ (High side) and 75mΩ (Low side) High Efficiency Up to 96% Efficiency @ 5V Input, 3.3V Output Up to 94% efficiency @ 12V Input, 3.3V Output Wide Input Voltage Range: 4.75V to 18V @ 3.0-A loading Wide Output Voltage Range: 0.923V to 14V @ 3.0-A loading ( 54Watt output @max) Low Output Ripple and Allows Ceramic Output Capacitor Thermal Shutdown Protection 340-KHz Switching Frequency(fsw) Cycle By Cycle Over Current Limit +/-1.5% High Accuracy Feedback Voltage Applications Wide Range of Applications for Low Voltage System - Digital TV Power Supply - High Definition Blu-ray Disc Players - Networking Home Terminal - Digital STB - Ideal for Portable Applications Descriptions The BLI9184 is a current mode synchronous buck converter, and has a proprietary W-mode™® Gm curvature circuit that enables fast transient response, enables the device to adopt to both low ESR output capacitors, such as POSCAP or SP-CAP, and ultra-low ESR ceramic capacitors. The BLI9184 operates from 4.75-V to 18-V Vin input, and the output voltage can be programmed between 0.923V to 14v with 3.0A output current, and +/-1.5% high accuracy output voltage. Due to 85mΩ (High side) and 75mΩ (Low side) integrated FETs, the BLI9184 works in high efficiency (up to 94% @12V Input, 3.3V output) .
