RT6203E Datasheet | Richtek

Description The RT6203E is an adaptive on-time mode synchronous Buck converter. The main control loop of the RT6203E uses an adaptive on-time mode control which provides a very fast transient response with no external ponents. The RT6203E operates from 4.5V to 18V VIN input. After the initial power-up, the output voltage can be changed by codes sent into the IC via an I2C patible VID control bus. There are special codes which can be used to program current limit level and thermal shutdown level. Shutdown and startup can be also programmed by special codes. The device also features an internal soft-start time. Output voltage is adjustable by VID code setting. VOUT range is between 0.6V to 1.62V Features - VID Control Range Via I2C patible Interface :  0.6V to 0.7V in 20m V Steps  0.7V to 1.2V in 10m V Steps  1.2V to 1.62V in 20m V Steps - Adjustable Current Limit - Adjustable Thermal Shutdown - Fast Transient Response - Steady 700k Hz Switching Frequency - Optimized for All Ceramic Capacitors - Internal Soft-Start - Input Under-Voltage Lockout - Thermal Shutdown - Ro HS pliant and Halogen Free Pin Configuration (TOP VIEW) EN VOUT PVCC VIN BOOT SW SCL SOP-8 (Exposed Pad) Applications - Industrial and mercial Low Power Systems - puter Peripherals - LCD Monitors and TVs - Green Electronics/Appliances - Point of Load Regulation for High-Performance DSPs, FPGAs, and ASICs Simplified Application Circuit VIN C1 Enable I2C Control SCL SDA BOOT VOUT PVCC L1 C2 C4 VOUT C3 Copyright ©2019 Richtek Technology Corporation.
