Overview
The TPS53015DGSR, produced by Texas Instruments, is a 4.5-V to 28-V input, D-CAP2™ synchronous step-buck converter. This device is designed to provide a cost-effective solution with a low external component count and low standby current. It operates using the D-CAP2 mode control, which offers fast transient response without requiring external compensation components. The TPS53015 supports a wide range of applications, including point-of-load regulation in low-power systems, and is available in a 3-mm × 3-mm 10-pin VSSOP package.
