The TPS6213x series, manufactured by Texas Instruments, includes highly efficient, easy-to-use synchronous step-down DC-DC converters optimized for applications requiring high power density. These converters operate within a wide input voltage range from 3 V to 17 V and are capable of delivering up to 3 A of continuous output current. The series comprises multiple part numbers, namely TPS62130, TPS62130A, TPS62131, TPS62132, and TPS62133, each offering unique output configurations—adjustable outputs for TPS62130 and TPS62130A, and fixed outputs of 1.8 V, 3.3 V, and 5.0 V for TPS62131, TPS62132, and TPS62133 respectively. Key features of the TPS6213x series include the advanced DCS-Control™ topology for improved transient response and high output voltage accuracy, a programmable soft start, seamless transition to power save mode, and selectable operating frequency (either 1.25 MHz or 2.5 MHz). The device also encapsulates robust protection mechanisms such as short circuit and overtemperature protection. Housed in a compact 3-mm x 3-mm QFN-16 package, the IC includes additional functions like a power-good output and 100% duty cycle mode for low dropout conditions. With a highly integrated design that requires minimal external components, the TPS6213x series is ideal for step-down regulation in various applications including standard 12-V rail supplies, POL supplies, embedded systems, and portable devices.
