SLVS952G –APRIL 2010–REVISED JANUARY 2017  
TPS6267x 500-mA/650-mA, 6-MHz High-Efficiency Step-Down Converter  
in Low Profile Chip Scale Packaging (Height < 0.4mm)

devices  
are  
high-frequency  
1
•
92% Efficiency at 6MHz Operation  
17μA Quiescent Current  
synchronous step-down dc-dc converters optimized  
for small battery-powered applications. Intended for  
low-power applications, the TPS6267x supports up to  
650-mA load current and allows the use of low cost  
chip inductor and capacitors.

Wide VIN Range From 2.3V to 4.8V  
6MHz Regulated Frequency Operation  
Spread Spectrum, PWM Frequency Dithering  
Best in Class Load and Line Transient  
±2% Total DC Voltage Accuracy  
Low Ripple Light-Load PFM Mode  
≥35dB VIN PSRR (1kHz to 10kHz)  
Simple Logic Enable Inputs  
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 1.05V to  
2.1V. 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.  
Supports External Clock Presence Detect Enable  
Input  
The PFM mode extends the battery life by reducing  
the quiescent current to 17μA (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.
