Micro Linear Intros ML4802 BiCMOS Device

April 18, 1999 by Jeff Shepard

Micro Linear Corp. (San Jose, CA) recently introduced the ML4802, a low-power BiCMOS device that contains an intelligent Green Mode circuit that is claimed to automatically increase power supply efficiency at light loads. The ML4802 works with a wide range of power line input voltages (85-265Vac), making it possible to design universal power supplies that automatically adapt to power outlets in any country. Pin-compatible with the industry-standard ML4841, the ML4802 also includes a power factor correction circuit that reduces supply harmonic radiation and protects systems from line noise and brownouts. According to Micro Linear, the circuit's patented LETE (Leading Edge/Trailing Edge) modulation method can cut the cost of the PFC high-voltage capacitor in half. The ML4802 is priced at $2.20 for a 16-pin plastic DIP in quantities of 1,000. It is also available in an SOIC narrow package.
