86% Efficiency at 6 MHz Operation  
DESCRIPTION  
38µA Quiescent Current  
The TPS6265x device is  
a
high-frequency  
Wide VIN Range From 2.3 V to 5.5 V  
6MHz Regulated Frequency Operation  
Best-In-Class Load and Line Transient  
±2% PWM DC Voltage Accuracy  
synchronous step-down dc-dc converter optimized for  
battery-powered portable applications. Intended for  
low-power applications, the TPS6265x supports up to  
800mA load current and allows the use of small, low  
cost inductors and capacitors.  
Automatic PFM/PWM Mode Switching  
Low Ripple Light-Load PFM  
I2C Compatible Interface up to 3.4 Mbps  
Pin-Selectable Output Voltage (VSEL)  
Internal Soft-Start, <150-µs Start-Up Time  
The device is ideal for mobile phones and similar  
portable applications powered by a single-cell Li-Ion  
battery. With an output voltage range adjustable via  
I2C interface down to 0.75V, the device supports  
low-voltage DSPs and processors core power  
supplies in smart-phones and handheld computers.  
Current Overload and Thermal Shutdown  
Protection  
The TPS6265x operates at  
a regulated 6MHz  
switching frequency and enters the efficiency  
optimized power-save mode operation at light load  
currents to maintain high efficiency over the entire  
load current range. In the shutdown mode, the  
current consumption is reduced to less than 3.5µA.  
•
•
Three Surface-Mount External Components  
Required (One MLCC Inductor, Two Ceramic  
Capacitors)  
Complete Sub 1-mm Component Profile  
Solution  
Total Solution Size <13mm2  
The serial interface is compatible with Standard,  
Fast/Fast Plus and High-Speed mode I2C  
specification allowing transfers at up to 3.4 Mbps.  
This communication interface is used for dynamic  
voltage scaling with voltage steps down to 12.5mV,  
for setting the output voltage or reprogramming the  
mode of operation (PFM/PWM or Forced PWM) for  
instance.
