Description
The TPS63710 is an inverting step-down dc-dc
converter generating a negative output voltage down
to -5.5 V. It provides an output current up to 1 A,
depending on the input-voltage to output-voltage
ratio. Its filtered reference system gives low 1/f noise
which is required in high performance telecommunication systems.
The TPS63710 operates with a fixed-frequency PWM
control topology. It has an internal current limit and a
thermal shutdown. The input voltage range of 3.1 V to
14 V allows the TPS63710 to be used in a variety of
applications where a negative output voltage is
generated from a, in absolute value, higher positive
input voltage. Synchronous rectification provides high efficiency
especially for small output voltages like -1.8 V, which
are typically used as a negative supply voltage for
high performance DACs and ADCs. A fixed switching
frequency of 1.5 MHz allows the use of small external
components and enables a small total solution size.
The TPS63710 comes in a 3-mm × 3-mm WSON
package that provides good thermal performance in
applications running at high ambient temperature
