DESCRIPTION  
The TPS6267x device is  
a
high-frequency  
synchronous step-down dc-dc converter optimized for  
battery-powered portable applications. Intended for  
low-power applications, the TPS6267x supports up to  
500-mA load current, and allows the use of low cost  
chip inductor and capacitors.  
Supports External Clock Presence Detect  
Enable Input  
•
•
Three Surface-Mount External Components  
Required (One 0603 MLCC Inductor, Two 0402  
Ceramic Capacitors)  
With a wide input voltage range of 2.3V to 4.8V, the  
device supports applications powered by Li-Ion  
batteries with extended voltage range. Different fixed  
voltage output versions are available from 1.0V to  
2.3V.  
Complete Sub 0.33-mm Component Profile  
Solution  
Total Solution Size <10 mm2  
The TPS6267x operates at a regulated 6-MHz  
switching frequency and enters the power-save mode  
operation at light load currents to maintain high  
efficiency over the entire load current range.  
•
•
Available in a 6-Pin NanoFree™ (CSP)  
Ultra-Thin Packaging, 0,4mm Max. Height  
The PFM mode extends the battery life by reducing  
the quiescent current to 17mA (typ) during light load  
operation. For noise-sensitive applications, the device  
has PWM spread spectrum capability providing a  
lower noise regulated output, as well as low noise at  
the input. These features, combined with high PSRR  
and AC load regulation performance, make this  
device suitable to replace a linear regulator to obtain  
better power conversion efficiency.
