FUNCTION
Fixed Duty Cycle Output. A push-pull output stage with an output
resistance of 160Ω, the FOUT pin swings from GND to V
lowest power operation, capacitive loads should be minimized
and resistive loads should be maximized.
No Connection.
Pulse-width Modulated Output. A push-pull output stage with an
output resistance of 160Ω, the PWMOUT pin is wired anti-phase
with respect to FOUT and swings from GND to V
power operation, capacitive loads should be minimized and
resistive loads should be maximized.
PWMOUT Enable and Duty Cycle Control Input. An analog input
pin, the V

PWM engine increases the TS3001’s nominal operating supply
current. To disable the TS3001’s PWM engine, CNTRL shall be
connected to V
Ground – Connect this pin to the system’s analog ground plane.
FOUT Programming Resistor Input. A 4.32MΩ resistor connected
from this pin to GND sets the TS3001’s internal oscillator’s output
period to 40μs (25kHz). For optimal performance, the
composition of the RSET resistor shall be consistent with
tolerances of 1% or lower. The RSET pin voltage is 0.3V at a 1V
supply.
Power Supply Voltage Input. While the TS3001 is fully specified
at 1V, the supply voltage range is 0.9V ≤ V
considered good engineering practice to bypass the V
a 0.1μF ceramic decoupling capacitor in close proximity to the
TS3001.
