Step-Down Converters:
V
IN
Range From 2.3V to 6V
The TPS65000 and TPS65001 are single chip Power
Management ICs for portable applications. Both
Spread Spectrum Clock (SSC) Generation
devices combine a single step-down converter with
for Reduced EMI
two low dropout regulators. The step-down converter
2.25MHz Fixed Frequency Operation
enters a low power mode at light load for maximum
600mA or 1A (TPS650061) Output Current efficiency across the widest possible range of load
currents. For low noise applications, the devices can

be forced into fixed frequency PWM via a pin. The
V
IN
Range From 1.6V to 6V
step-down converter allows the use of a small
Adjustable Output Voltage
inductor and capacitors to achieve a small solution
size. The step-down converter has Power Good
Up to 300mA Output Current
status output that can be used for sequencing. The
Separate Power Inputs and Enables
LDOs are capable of supplying 300mA, and can
Supply Voltage Supervisor (TPS65001)
operate with an input voltage range between 1.6V
and 6V, allowing them to be supplied from the
Manual Reset Input for Push Button
step-down converter or directly from the main battery.
Adjustable Reset Time
The step-down converter and the LDOs have
Adjustable Reset Voltage
separate voltage inputs and enables, allowing for
design and sequencing flexibility.
3mm × 3mm 16-Pin QFN (TPS65000)
3mm × 3mm 20-Pin QFN (TPS65001)
The TPS65000 is available in a 16-pin leadless
package (3mm × 3mm QFN).
APPLICATIONS
The TPS65001 extends functionality by adding a
Point of Load
Supply Voltage Supervisor (SVS). The SVS allows
Embedded Processor Power
maximum flexibility by having the reset voltage set
with two external resistors, and the reset time set by
Cell Phones, Smart-Phones
a small external capacitor. In addition, an active low

to a push button for external control.
The TPS65001 is available in a 20-pin leadless
package (3mm × 3mm QFN).
