800-mA, 3-MHz SYNCHRONOUS STEP-DOWN CONVERTER  
WITH I2C™ COMPATIBLE INTERFACE IN CHIP SCALE PACKAGING  
FEATURES  
DESCRIPTION  
•
•
•
•
•
•
•
•
88% Efficiency at 3-MHz Operation  
800-mA Output Current at VI = 2.7 V  
3-MHz Fixed Frequency Operation  
Best in Class Load and Line Transient  
Complete 1-mm Component Profile Solution  
±2% PWM DC Voltage Accuracy  
35-ns Minimum On-Time  
The TPS6235x device is  
a
high-frequency  
synchronous step-down dc-dc converter optimized  
for battery-powered portable applications. Intended  
for low-power applications, the TPS6235x supports  
up to 800-mA load current and allows the use of  
small, low cost inductors and capacitors.  
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 0.6 V, the device supports  
low-voltage DSPs and processors core power  
supplies in smart-phones, PDAs, and handheld  
computers.  
Efficiency Optimized Power-Save Mode  
(Light PFM)  
•
Transient Optimized Power-Save Mode  
(Fast PFM)  
•
•
•
•
28-µA Typical Quiescent Current  
I2C Compatible Interface up to 3.4 Mbps  
Pin-Selectable Output Voltage  
The TPS6235x operates at 3-MHz fixed 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 2 µA.  
Synchronizable On the Fly to External  
Clock Signal  
•
Available in a 10-Pin QFN (3 x 3 mm) and  
12-Pin NanoFree™ (CSP) Packaging  
The serial interface is compatible with Fast/Standard  
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 12.5 mV, for reprogramming  
the mode of operation (Light PFM, Fast PFM or  
Forced PWM) or disable/enabling the output voltage.
