PIN FUNCTIONS

PIN

NAME

FUNCTION

1

FOUT

Fixed Duty Cycle Output. A push-pull output stage with an output

resistance of 160

Ω, the FOUT pin swings from GND to V

lowest power operation, capacitive loads should be minimized

and resistive loads should be maximized.

2

NC

No Connection.

3

PWMOUT

Pulse-width Modulated Output. A push-pull output stage with an

output resistance of 160

Ω, the PWMOUT pin is wired anti-phase

power operation, capacitive loads should be minimized and

resistive loads should be maximized.

4

CNTRL

PWMOUT Enable and Duty Cycle Control Input. An analog input

’s PWM engine

and controls the duty cycle at PWMOUT from 12%

PWM engine increases the TS3001

’s nominal operating supply

current. To disable the TS3001

’s PWM engine, CNTRL shall be

5,6

GND

Ground

– Connect this pin to the system’s analog ground plane.

7

RSET

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.

8

VDD

Power Supply Voltage Input. While the TS3001 is fully specified

a 0.1μF ceramic decoupling capacitor in close proximity to the

TS3001.
