Product Description
STMicroelectronics L5991D is a 5-channel pulse-width modulation (PWM) controller housed in a 16-pin SOIC surface mount package. This PWM controller utilizes current mode control technology and is capable of switching frequencies up to 1000 kHz, making it suitable for a variety of power management applications including isolated and non-isolated AC-DC and DC-DC converter topologies such as fly-back, forward, and quasi-resonant converters.
The device provides 5 output channels with an output current rating of 1.5 A and an output voltage of approximately 5.07 V, operating on supply voltages ranging from 12 V minimum to 20 V maximum. It offers a maximum duty cycle of 85%, allowing efficient power delivery with minimal losses.
Designed for rugged industrial environments, the L5991D operates reliably over a wide temperature range from -40°C to 150°C. Its compact dimensions of 10 mm length, 4 mm width, and 1.65 mm height facilitate integration into high-density power supply designs.
The PWM controller is robustly engineered with integrated protections to enhance reliability in demanding manufacturing, industrial automation, and power management systems. It supports various Switch Mode Power Supply (SMPS) configurations including symmetric and asymmetric topologies.
Maximum switching frequency: 1000 kHz for high efficiency power regulation. Low supply current of 10 mA reduces overall power consumption. 5 outputs ensure multi-channel PWM control capability. Surface mount SOIC package suitable for automated PCB assembly.
Wide operating temperature range for use in industrial applications. Current mode control provides improved transient response and noise immunity. Compact form factor aids in space-saving electronic designs.
This PWM controller is ideal for use in industrial machines, power supplies, manufacturing equipment, and other electronic systems needing reliable multi-channel PWM control with precise electrical characteristics.
