DESCRIPTION  
D
Synchronizable Fixed-Frequency PWM or  
Automatic Pulsed Frequency Modulation  
(PFM) Mode  
The TPS43000 is a high-frequency, voltage-mode,  
synchronous PWM controller that can be used in buck,  
boost, SEPIC, or flyback topologies. This highly flexible,  
full-featured controller is designed to drive a pair of  
external MOSFETs (one N-channel and one  
P-channel), enabling it for use with a wide range of  
output voltages and power levels. With an automatic  
PFM mode, a shutdown current of less than 1 µA, a  
sleep-mode current of less than 100 µA and a full  
operating current of less than 2 mA at 1 MHz, it is ideal  
for building highly efficient, dc-to-dc converters.

TYPICAL BUCK APPLICATION  
VIN  
TPS43000  
The TPS43000 operates over a wide input voltage  
range of 1.8 V to 9.0 V. Typical power sources are  
distributed power systems, two to four nickel or alkaline  
batteries, or one to two lithium-ion cells. It can be used  
to generate regulated output voltages from as low as  
0.8 V to 8 V or higher. It operates either in a  
fixed-frequency mode, where the user programs the  
frequency (up to 2 MHz), or in an automatic PFM mode.  
In the automatic mode, the controller goes to sleep  
when the inductor current goes discontinuous, and  
wakes up when the output voltage has fallen by 2%. In  
this hysteretic mode of operation, very high efficiency  
can be maintained over a very wide range of load  
current. The device can also be synchronized to an  
external clock source using the dual function SYNC/SD  
input pin.
