DESCRIPTION  
The TPS62650-Q1 device is  
synchronous step-down dc-dc converter optimized for  
battery-powered portable applications. Intended for  
low-power applications, the TPS62650-Q1 supports  
up to 800mA load current and allows the use of  
small, low cost inductors and capacitors.

86% Efficiency at 6-MHz Operation  
38-μA Quiescent Current  
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  
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.  
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 TPS62650-Q1 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.
