Texas Instruments TPS54526 5.5A Synchronous Step-Down Converter with Eco-Mode™

Texas Instruments TPS54526 5.5A Synchronous Step-Down Converter with Eco-Mode™

Texas Instruments TPS54526 5.5A Synchronous Step-Down Converter with Eco-Mode™ enables system designers to complete the suite of various end equipment's power bus regulators with a cost effective, low component count, low standby current solution. The main control loop for TI TPS54526 Step-Down Converter uses 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 conditions and Eco-mode™ operation at light loads. Eco-mode allows the TPS54526 to maintain high efficiency during lighter load conditions. The TPS54526 also has a proprietary circuit that enables the device to adopt to both low equivalent series resistance (ESR) output capacitors, such as POSCAP, SP-CAP, and ultra-low ESR ceramic capacitors. This TI device also features an adjustable soft start time and a power good function.
