Introduction

AI Translation

TPS566235 is a cost-effective, high-voltage input, high-efficiency synchronous buck converter with integrated FETs. The device enables system designers to complete a kit containing various end-equipment power bus regulators with a cost-effective, low component count, and low standby current solution.

The TPS566235 uses D-CAP3™ mode control, which achieves fast transient response and excellent line/load regulation without external compensation components. The device features a dedicated circuit to support low ESR output capacitors (such as dedicated polymer capacitors and ultra-low ESR ceramic capacitors). The control topology supports seamless switching between CCM mode under heavy load conditions and DCM operation under light load conditions. Under light load conditions, three operating modes can be configured via the MODE pin: Eco-Mode™, Out-Of-Audio™ (OOA), and FCCM. OOA mode is a unique control feature that keeps the switching frequency above the audible frequency range while minimizing the impact on efficiency.

The TPS566235 supports pre-biased startup and a power-good indicator. It provides comprehensive protection including OVP, UVP, OCP, OTP, and UVLO. The device is available in a 3.0mm × 2.0mm HotRod™ VQFN package, rated for a junction temperature range of -40°C to 125°C.
