TPS563252DRLR

TPS56325x is a simple, easy-to-use, high-efficiency, high-power-density synchronous buck converter with an input voltage range of 3V to 17V, supporting up to 3A continuous output current over an output voltage range of 0.6V to 10V. The TPS56325x employs D-CAP3 control mode for fast transient response and supports low-ESR output capacitors with no external compensation required. The device supports duty cycle operation up to 95%. Integrated bootstrap capacitor helps achieve single layer PCB and can save total BOM cost. The TPS563252 operates in Eco-mode to maintain high efficiency at light loads. The TPS563257 operates in FCCM mode to maintain a consistent switching frequency and low output ripple across all load conditions. The device integrates comprehensive hiccup-mode OVP, OCP, UVLO, OTP, and UVP protection. The device is available in a 1.6mm×1.6mm SOT-563 package. The rated junction temperature range is -40°C to 125°C.
