2• Step-Down Converters: DESCRIPTION
– VIN 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
• LDOs:
be forced into fixed frequency PWM via a pin. The
– VIN 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
– Up to 300mA Output Current
size. The step-down converter has Power Good
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
– Manual Reset Input for Push Button and 6V, allowing them to be supplied from the
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
• 3mm × 3mm 16-Pin QFN (TPS65000) design and sequencing flexibility.
• 3mm x×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
• Cell Phones, Smart-Phones with two external resistors, and the reset time set by
a small external capacitor. In addition, an active low
• PDAs, Pocket PCs
Manual Reset input allows the SVS to be connected
• Portable Media Players
to a push button for external control.
The TPS65001 is available in a 20-pin leadless
package (3mm × 3mm QFN).
