Descripción general
Description
Features
1. Current Mode Control: Provides improved performance for voltage regulation, transient response, and loop stability.
2. Fixed-Frequency Operation: Typically operates at a fixed frequency around 100 kHz, depending on external components.
3. High-Performance Current Limiting: Employs cycle-by-cycle current limiting to protect against overcurrent conditions.
4. Low Start-Up and Operating Current: Features low start-up (0.5 mA typical) and operating current (17 mA maximum) to enhance efficiency.
5. Built-In Soft Start: Gradually increases the duty cycle at start-up to prevent current spikes.
6. Undervoltage Lockout (UVLO): Ensures the controller starts up only when the supply voltage is within safe limits.
7. Pin Configuration: Comes in an 8-pin DIP package, which is easy to integrate into various circuit designs.
8. Output Drive Capability: Can drive power MOSFETs directly, supporting medium to high power applications.
These features make the TL3842P suitable for use in offline and DC-DC converter applications, such as in power supplies for consumer electronics and industrial systems.
Package
Pinout
1. Pin 1 (COMP): Compensation. Used to compensate the control loop.
2. Pin 2 (VFB): Voltage Feedback. Receives the feedback voltage from the power supply output to regulate the PWM.
3. Pin 3 (Current Sense): Monitors the current through the power MOSFET and provides current limiting.
4. Pin 4 (RT/CT): Timing Resistor/Capacitor. Sets the oscillator frequency.
5. Pin 5 (GND): Ground. Common return path for power and signals.
6. Pin 6 (Output): Drives the gate of the power MOSFET.
7. Pin 7 (VCC): Supply Voltage. Powers the IC.
8. Pin 8 (VREF): Reference Voltage. Provides a stable voltage reference for internal circuitry.
These pins work together to implement a control scheme that regulates power supply output by varying PWM duty cycles based on feedback and current sensing inputs.
