91% Efficiency at 6MHz Operation
The
TPS6266x
device
is
a
high-frequency
31mA Quiescent Current
synchronous step-down dc-dc converter optimized for
Wide VIN Range From 2.3V to 5.5V
battery-powered portable applications. Intended for
6MHz Regulated Frequency Operation
low-power applications, the TPS6266x supports up to
1000mA peak load current, and allows the use of low
Best in Class Load and Line Transient
cost chip inductor and capacitors.
±2% Total DC Voltage Accuracy
With a wide input voltage range of 2.3V to 5.5V, the
Automatic PFM/PWM Mode Switching
device supports applications powered by Li-Ion
Low Ripple Light-Load PFM Mode
batteries with extended voltage range. Different fixed
Fast Turn-On Time, <60-ms Start-Up Time
voltage output versions are available from 1.2V to
2.3V.
Integrated Active Power-Down Sequencing
(Optional)
The TPS6266x operates at a regulated 6-MHz
switching frequency and enters the power-save mode
Current Overload and Thermal Shutdown
operation at light load currents to maintain high
Protection
efficiency over the entire load current range.
Three Surface-Mount External Components
Required (One MLCC Inductor, Two Ceramic
The PFM mode extends the battery life by reducing
the quiescent current to 31mA (typ) during light load
Capacitors)
and
standby
operation.
For
noise-sensitive
Complete Sub 1-mm Component Profile
applications, the device can be forced into fixed
Solution
frequency PWM mode by pulling the MODE pin high.
Total Solution Size <12 mm2
In the shutdown mode, the current consumption is
reduced to less than 1mA.
Available in a 6-Pin NanoFree (CSP)
The TPS6266x is available in an 6-pin chip-scale
