FUNCTION
Fixed Frequency Output. A push-pull output stage with an
output resistance of 160Ω. FOUT pin swings from GND to
VDD. For lowest power operation, capacitance loads
should be minimized and resistive loads should be
maximized.
Non-Connect.
Ground. Connect this pin to the system’s analog ground
plane.
Power Supply Voltage Input. The supply voltage range is
1.55V ≤ V_DD ≤ 5.25V. Bypass this pin with a 0.1uF ceramic
coupling capacitor in close proximity to the TS3006.
FOUT Programming Resistor Input. A 4.32MOhm resistor
connected from this pin to ground sets the T3003’s internal
oscillator’s output period to 40µs (25KHz). For optimal
performance, the composition of the RSET resistor shall
be consistent with a tolerance of 1% or lower. The RSET
pin voltage is approximately 0.3V.
