Description and Introduction

Current-Mode PWM Controller The AIC3842CN is a pulse width modulation (PWM) controller IC manufactured by AIC (Analog Integrations Corporation). It is commonly used in switch-mode power supplies (SMPS). Key specifications include:

- **Input Voltage Range**: Typically operates with a supply voltage range of 8V to 30V.
- **Output Drive**: Provides a totem-pole output capable of driving power MOSFETs or IGBTs.
- **Switching Frequency**: Adjustable, typically up to 500 kHz.
- **Duty Cycle**: Adjustable, with a maximum duty cycle typically around 50%.
- **Current Sensing**: Includes a current sense input for overcurrent protection.
- **Error Amplifier**: Features an internal error amplifier for feedback control.
- **Soft Start**: Includes a soft-start function to reduce inrush current during startup.
- **Protection Features**: Includes under-voltage lockout (UVLO), over-current protection (OCP), and over-temperature protection (OTP).
- **Package**: Typically available in an 8-pin DIP (Dual In-line Package) or SOIC (Small Outline Integrated Circuit) package.

These specifications make the AIC3842CN suitable for a variety of power supply applications, including AC-DC converters, DC-DC converters, and battery chargers.
