TL3845BP

Texas Instruments · AC-DC Controllers And Regulators · PDIP-8

TL3845BP from Texas Instruments, in a PDIP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 COMP bidirectional Error amplifier compensation pin; the error amplifier output sink current is limited to 10 mA maximum.
2 VFB input Error amplifier input; the analog input voltage range is -0.3 V to 6.3 V absolute maximum and 0 V to 5.5 V recommended.
3 ISENSE input Current sense comparator input; the analog input voltage range is -0.3 V to 6.3 V absolute maximum and 0 V to 5.5 V recommended.
4 RT/CT bidirectional Oscillator RC input with a recommended input voltage range of 0 V to 5.5 V.
5 GND power_in Device power supply ground terminal.
6 OUTPUT output PWM output with a recommended output voltage range of 0 V to 30 V and an average output current of up to 200 mA.
7 VCC power_in Device positive voltage supply; the absolute maximum supply voltage is 30 V for a low-impedance source.
8 VREF power_in Oscillator voltage reference output; the recommended reference output current is -20 mA.
