The TPS54527 enables Response system designers to complete the suite of various • Low Output Ripple and Allows Ceramic Output end equipment’s power bus regulators with a cost Capacitor effective, low component count, low standby current • Wide Input Voltage Range: 4.5 V to 18 V solution. The main control loop for the TPS54527 uses the D-CAP2 mode control which provides a fast • Output Voltage Range: 0.76 V to 6 V transient response with no external compensation • Highly Efficient Integrated FETs Optimized for components. The TPS54527 also has a proprietary Lower Duty Cycle Applications: 65 mΩ (High Side) circuit that enables the device to adopt to both low and 36 mΩ (Low Side) equivalent series resistance (ESR) output capacitors, such as POSCAP or SP-CAP, and ultra-low ESR • High Efficiency: Less Than 10 µA at Shutdown ceramic capacitors. The device operates from a 4.5-V • High Initial Bandgap Reference Accuracy to 18-V input. The output voltage can be programmed • Adjustable Soft Start from 0.76 V to 6 V. The device also features an • Prebiased Soft Start adjustable soft-start time. The TPS54527 is available in the 8-pin DDA package, and designed to operate • 650-kHz Switching Frequency from –40°C to 85°C. • Cycle-by-Cycle Overcurrent Limit (1) Device Information 2 Applications PART NUMBER PACKAGE BODY SIZE (NOM) • Wide Range of Applications for Low Voltage TPS54527 SO PowerPAD (8) 4.89 mm × 3.90 mm System (1) For all available packages, see the orderable addendum at – Digital TV Power Supply the end of the data sheet. – High Definition Blu-ray Disc™ Players – Networking Home Terminal – Digital Set Top Box (STB) Load Transient Response Simplified Schematic Vout (50 mV/div) TPS54527 Iout (2 A/div) Copyright © 2016, t - Time - 100 ms/div 1 An IMPORTANT NOTICE at the end of this data sheet addresses availability, warranty, changes, use in safety-critical applications, intellectual property matters and other important disclaimers.
