ETA8110S2G

ETA8110 18V, 2A, COT Synchronous Step-Down Converter in SOT23-6 DESCRIPTION FEATURES ETA8110 is a wide input range, high-efficiency and highfrequency DC-to-DC step-down switching regulator, capable of delivering up to 2A of output current. It adopts an adaptive COT control scheme that enables very fast transient response and provides a very smooth transition when the output varies from light load to heavy load. The adaptive COT control also maintains a constant switching frequency across line and load. ETA8110 is available in SOT23-6 package.  Wide Input Voltage Range: 3.5V-18V  Adaptive COT Control  Forced PWM Mode  Capable of Delivering 2A Output  Ultra-fast Load Transient Response  High Efficiency Synchronous Operation  Low Rdson Internal power FETs  No External Compensation Needed APPLICATIONS  Thermal Shutdown and UVLO  Available in SOT23-6 Package RoHS Compliant    LCD TV Set Top Box IP CAM  TYPICAL APPLICATION 10nF 1 BST VIN 12V 2.2uH 5 IN EN R1 110K ETA8110 10uF VOUT 5V SW 6 47pF Optional 22uF FB 3 4 EN GND 2 R2 15K Vout= R1+R2 x0.6(V) R2 * R2 has to be between 1KOhm to 70KOhm ORDERING INFORMATION www.etasolution.com PART No. PACKAGE TOP MARK Pcs/Reel ETA8110S2G SOT23-6 JG|YW 3000 1 Empower, Transcend, Achieve! ETA8110 PIN CONFIGURATION ABSOLUTE MAXIMUM RATINGS (Note: Exceeding these limits may damage the device.
