BL8038 Datasheet | BELLING

1A 2MHz 5.5V Synchronous Buck Converter DESCRIPTION Features The BL8038 is a high-efficiency, DC-to-DC stepdown switching regulators, capable of delivering up to 1A of output current. The device operates from an input voltage range of 2.6V to 5.5V and provides an output voltage from 0.6V to Vin. Working at a fixed frequency of 2MHz allows the use of small external ponents, such as ceramic input and output caps, as well as small inductors, while still providing low output ripples. This low noise output along with its excellent efficiency achieved by the internal synchronous rectifier, making BL8038 an ideal replacement for large power consuming linear regulators. Internal soft-start control circuitry reduces inrush current. Short-circuit and thermal shutdown protection improves design reliability. The BL8038 is available in SOT23-5. - High efficiency: up to 97% - Output current: up to 1A - 2MHz switching frequency - Low dropout 100% duty operation - Internal pensation and soft-start - Current mode control - Reference 0.6V - Logic control shutdown (IQ<1u A) - Thermal shutdown, UVLO - Available in SOT23-5 APPLICATIONS - Cellular phones - Digital cameras - MP3 and MP4 players - Set top boxes - Wireless and DSL modems - USB supplied devices in notebooks - Portable devices TYPICAL APPLICATION VIN 2.6V to 5.5V 10u F 1u H/2.2u...
