- Wide input voltage range: 2.97V to 40V, suitable for automotive and industrial power supplies
- Compact SOIC-8 package enabling high-density board designs
- Supports boost, flyback, SEPIC, and other switching converter topologies
- Low minimum on-time enabling high-frequency operation up to hundreds of kHz
Applications
The LM3488MM is widely used in DC-DC boost and flyback converter designs for industrial power supplies, automotive electronics, and battery-powered systems. Its wide input voltage range and current-mode control make it ideal for LED drivers, point-of-load regulators, and telecom power modules. Engineers also deploy it in SEPIC converters where non-inverting wide-range voltage conversion is required.

Frequently Asked Questions
What is the input voltage range of the LM3488MM?
The LM3488MM supports an input voltage range of 2.97V to 40V, with a nominal operating voltage of 12V. This wide range makes it suitable for automotive (12V/24V bus), industrial 24V rails, and battery-powered applications where input voltage varies significantly.
What switching topologies are supported by the LM3488MM?
The LM3488MM supports multiple non-synchronous switching topologies including boost, flyback, SEPIC, and Cuk converters. Its current-mode PWM control architecture with external compensation allows designers to optimize loop stability across all these topologies.
What package does the LM3488MM come in?
The LM3488MM is available in an 8-pin SOIC small outline package (JESD-30 code: S-PDSO-G8). This compact surface-mount package is RoHS-compliant (Pb-free) and well-suited for high-density PCB designs in space-constrained applications.
Are there pin-compatible alternatives to the LM3488MM?
Pin-compatible or functionally similar alternatives include the LM3478 and UC3843 family of current-mode PWM controllers. However, always verify input voltage range, oscillator frequency range, and compensation network requirements before substituting, as minor differences in internal thresholds may affect loop stability.
