TL3842P DATASHEET PDF

Some of the internally implemented circuits are an undervoltage lockout UVLO , featuring a start-up current of less than 1 mA, and a precision reference trimmed for accuracy at the error amplifier input. Other internal circuits include logic to ensure latched operation, a pulse-width modulation PWM comparator that also provides current-limit control , and a totem-pole output stage designed to source or sink high-peak current. PDF , 1. Extract from the document. Designed as the next generation '42, the UCC also has differences that prevent a simple drop-in substitute.

Usually microcontrollers and digital electronics requires a higher current at lower operating voltages so it becomes important to reduce the induction losses of power supply by making the resistance of the current sensing element as low as possible which is achieved by using a current mode controller. Current mode controllers are highly reliable with fast cycle to cycle current sensing for output short circuit and overload protection, so they can be used for the protection purposes as well.

Current mode controllers are being used in digital cameras, Bluetooth devices, cellular phones, auxiliary power supplies. Positive power supply ranging from 2. Output range of the output PWM is 0 to 30 Volts. Timing and bypass capacitors should be connected close to the GND terminal in a single point ground all the grounds of the circuit should be made common. External compensation components for stability should also be placed close to the IC. Surface mount components are recommended here as well.

These components should not be located very much close to the inductor because it will induce a magnetic field around it. The common ground of the complete network should be placed at the ground terminal of the device to make a reference point. While using the network with the TLp it should be observed that the output current does not exceed 25 mA that is the maximum bearable current by the device. Tlp has a very good frequency response. It can carry out smooth function for the frequency ranging from kHz to kHz.
