SD4840P Datasheet Pwm Controller

Manufacturer: Silan Microelectronics

Overview: SD4840/4841/4842/4843/4844 CURRENT MODE PWM CONTROLLER WITH BUILT-IN HIGH VOLTAGE.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

SD4840/4841/4842/4843/4844 is a current mode PWM controller with low standby power and low start current for power switch.

In standby mode, the circuit enters burst mode to reduce the standby power dissipation.

The switch frequency is 67KHz with ±2.5 KHz jitter frequency for low EMI.

Key Features

  • Lower start-up current (Typ.6μA).
  • Frequency jitter for low EMI.
  • Overcurrent protection.
  • Overvoltage protection.
  • Undervoltage lockout.
  • Built-in temperature protection.
  • Built-in high voltage MOSFET www. DataShee.
  • t4AUu. ctomrestart mode.
  • Built-in soft start.
  • Burst mode operation.
  • Cycle by cycle current limit.
