The TPS54560BQDDAQ1 is a 5-A, 60-V DC-DC step down regulator equipped with Texas Instruments’ integrated FETs (iFETs). It supports a wide input voltage range of 4.5 to 60 V and features programmable switching frequency in the range of 125 kHz to 2 MHz. The TPS54560BQDDAQ1 is a highly integrated power solution for applications such as servers, storage, industrial equipment, and renewable energy systems, including photovoltaic systems and fuel cells.

The TPS54560BQDDAQ1 can be used to deliver clean, well-regulated power for any electronic application needing a power supply, from small consumer electronics to complex industrial machinery. It supports a wide input voltage range and output voltage range covering all the popular system voltages from 2.5 to 12 VDC. The integrated iFETs provide efficiency improvements, reduce the external component count, and reduce system cost. It also features an adjustable switching frequency within the range of 125 kHz to 2 MHz, allowing flexibility in design and efficiency optimization. The device also features current and thermal protection, as well as short-circuit protection.

The TPS54560BQDDAQ1 operates on a quasi-resonant power stage that combines the features of both CCM (continuous conduction mode) and DCM (discontinuous conduction mode) operation. This mode of operation improves efficiency by providing shorter on and off times than conventional methods and reduces the switching losses. The CCM/DCM operation reduces the size of the external components such as inductors, capacitors and FETs, resulting in a smaller and more efficient power supply. It also provides a higher load current step-up conversion and works with most topologies such as buck, boost, flyback and SEPIC.

The TPS54560BQDDAQ1 is a highly integrated device combining a high-side and a low-side switch with a controller, regulator, gate driver and power stage. It can be used to provide a regulated output voltage from an input voltage source ranging from 4.5 V to 60 V. It operates in two modes: quasi-resonant mode and burst-mode. It also features an adjustable oscillator frequency, allowing the design engineer to optimize efficiency at the same time reducing system cost. The active current clamping helps to reduce the peak current and the voltage RDS(on) of the external switch reduces the stress on the switches and improves the efficiency at light loads. The operating temperature range is -40°C to +125°C.

The TPS54560BQDDAQ1 is a highly integrated DC-DC step down regulator suitable for a wide variety of application. It is capable of providing a regulated output voltage from an input voltage source ranging from 4.5 V to 60 V. It operates in quasi-resonant mode and burst-mode, and supports a wide range of switching frequencies. It provides protection including short-circuit protection and current limiter. The integrated iFETs reduce system cost and increase efficiency and the operating temperature range of -40°C to +125°C make the device suitable for a wide range of applications.
