Description
General part information
TPS53015 Series
The TPS53015 device is a single, adaptive on-time D-CAP2 ™ mode synchronous buck controller. The device enables system designers to complete the suite of various end equipment power bus regulators with cost effective low external component 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 compensation components. The adaptive on-time 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 ultra-low 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 10-pin VSSOP (DGS) package and is specified for an ambient temperature range of –40°C to 85°C.
