UC3843 PWM Controller IC DIP – Current Mode Control, Low Startup, DIP-8
UC3843 PWM Controller IC DIP is a current-mode PWM controller designed for accurate and stable power regulation in SMPS and DC-DC converters. With a low startup current of less than 1 mA and integrated undervoltage lockout (UVLO), it supports energy-efficient designs across industrial and consumer electronics. The built-in oscillator enables operation up to 500 kHz, and the totem-pole output allows easy driving of N-channel MOSFETs. Its DIP-8 package ensures compact placement in circuit layouts, making it suitable for power control in automation, battery-powered systems, and renewable energy.
Offering precise regulation through an internal error amplifier and 2.5V reference voltage, the UC3843 PWM Controller IC DIP simplifies design while maintaining performance. This IC is commonly used in power supplies, automotive electronics, and embedded systems that demand high efficiency and control.
