Product Summary

The BIT3193G is a high performance PWM controller. The logic high output of pin PWMOUT is made by an 2.5V DC voltage and the floating state makes the logic low portion. MODSEL pin provides the polarity selection of LF_PWM generator. If MODSEL pin is 0V, a 0% duty cycle is obtained when PWMDC < 1.0V. If this pin is pulled to IC VDD level, 0% duty cycle is obtained while PWMDC> 2.5V.

Parametrics

BIT3193G absolute maximum ratings: (1)Supply Voltage VDD: -0.3 to + 9 V; (2)Ground GND: ±0.3 V; (3)Input pin Voltage: -0.3 to VDD+0.3 V; (4)Chip Consumed Current 8V Supply Voltage Ta=25℃: 4 mA; (5)Operating Frequency: 50 to 400 KHz.

Features

BIT3193G features: (1)The inverting input of the error amplifier; (2)Output of the error amplifier; (3)A switch that connected to the high frequency triangle wave generator; (4)This switch is open while ISEN pin <13V An external resistor connected here may change the operation frequency of CTOSC in open load situation; (5)An external capacitor connected here can set the frequency of high frequency PWM controller.
