The device enables system designers to plete the suite of various end equipment power bus regulators with cost effective low external ponent count and low standby current solution. The main control loop for the TPS53015 uses the D-CAP2 mode control which provides a very fast transient response with no external pensation ponents. The adaptive ontime control supports seamless transition between PWM mode at higher load condition and Eco-mode™ operation at light load. Eco-mode operation allows the device to maintain high efficiency during lighter load conditions. The device is also able to adapt to both low equivalent series resistance (ESR) output capacitors such as POSCAP or SP-CAP and ultralow ESR ceramic capacitors. The device provides convenient and efficient operation with input voltages from 4.5 V to 28 V and output voltage from 0.77 V to 7 V. The TPS53015 is available in the 3-mm × 3-mm 10pin VSSOP (DGS) package and is specified for an ambient temperature range of - 40°C to...
