Qualified for Automotive Applications
High Efficiency—up to 95%
The
TPS62410
device
is
a
synchronous
dual
step-down DC-DC converter optimized for battery
VIN Range From 2.5 V to 6 V
powered
portable
applications.
It
provides
two
2.25 MHz Fixed Frequency Operation
independent output voltage rails powered by 1-cell
Output Current 2 x 800mA
Li-Ion or 3-cell NiMH/NiCD batteries. The device is
also suitable to operate from a standard 3.3V or 5V
Adjustable Output Voltage From 0.6 V to VIN
voltage rail.
EasyScale Optional One Pin Serial Interface
With an input voltage range of 2.5V to 6V, the
for Dynamic Output Voltage Adjustment
TPS62410 is ideal to power portable applications like
Power Save Mode at Light Load Currents
smart phones, PDAs, and other portable equipment.
180° Out of Phase Operation
With the EasyScale serial interface the output
Output Voltage Accuracy in PWM Mode ±1%
voltages
can
be
modified
during
operation.
It
Typical 32 A Quiescent Current for both
therefore supports Dynamic Voltage Scaling for low
Converters
power DSP and processors.
100% Duty Cycle for Lowest Dropout
The TPS62410 operates at 2.25MHz fixed switching
Available in a 10-Pin QFN (3×3mm)
frequency and enter the Power Save Mode operation
at light load currents to maintain high efficiency over
the
entire
load
current
range.
For
low
noise
applications the devices can be forced into fixed
frequency PWM mode by pulling the MODE/DATA
pin
high.
In
the
shutdown
mode,
the
current
consumption is reduced to 1.2A. The device allows
the use of small inductors and capacitors to achieve a
small solution size.
The TPS62410 is available in a 10-pin leadless
package (3×3mm QFN).
