10 / 10 page 4-110 TELCOM SEMICONDUCTOR, INC. PIN DESCRIPTION Pin No. Symbol Description 1 CURRENT LIMIT, SOFT START Pin for setting the peak current limit threshold of sense inputs pin 3 and pin 4. A second function of this pin is for Soft-Start programming with a capacitor between this pin and ground, pin 12. 2 VREF Pin is an output for the reference supply voltage of 5.1 volts. This reference can supply a minimum of 20mA of output current. 3 – CURRENT SENSE Pin is the current sense inverting input for sensing peak current of the pass transistor through the series current monitor resistor. 4 + CURRENT SENSE Pin is the non-inverting input for sensing peak current of the pass transistor. The positive end of the current sense resistor is connected here. 5 + ERROR AMP Pin is the non-inverting input for sensing voltage feedback from output for voltage regulation. 6 – ERROR AMP Pin is the inverting input for sensing the reference voltage to regulate the output. 7 COMPENSATION Pin for compensating the feedback loop response. 8 CT Pin is the input for timing capacitor, CT, to set oscillator frequency in conjunction with 9 resistor RT, input. A second function is for setting the crossover dead time of the outputs, pins 11 and 14. 9 RT Pin is the input for the timing resistor, RT, to set oscillator frequency by setting the (constant) current charge rate for capacitor CT. 10 SYNC Pin is the input or output for the oscillator synchronization pulse. 11 OUTA Pin is the output drive of phase A to drive push pull transistor A. 12 GND Pin is the ground return path for all input and output signals. 13 VDD Pin is the supply power input terminal for the output drivers. 14 OUTB Pin is the output drive of phase B to drive push pull transistor B. 15 VIN Pin is voltage bias supply input for all circuits except the output drivers 16 SHUT Pin is an input for shutdown when a 350mV threshold is exceeded: both output drives will then be terminated.
