Dual non-synchronous PWM buck regulator IC from Micrel for consumer electronic apps

Micrel has introduced the MIC4782, a new dual non-synchronous PWM buck regulator IC suitable for consumer applications such as wired and wireless broadband communication equipments, printers, HD set top boxes, computing peripherals and low power FPGAs.

The key features of the MIC4782 regulator IC are,

Operating at 1.8 MHz, with a maximum load current of 2A per channel
More than 92 % of efficiency
Output voltage can be adjusted down to 0.6V and the device can operate with a maximum duty cycle of 100 percent for use in low dropout conditions
Ultra-fast operation and internal compensation allows ultra-fast transient response
High PWM frequency of operation for small and cost-effective LC components

"Overall system cost continues to be forefront in the minds of designers, particularly in multiple-rail consumer applications," noted Andrew Cowell, vice president of analog marketing, Micrel. "The independently-controlled dual channel MIC4782 allows customers to address multiple-rail step-down requirements in a cost-effective manner. The integrated high-side FET, one each per channel, along with the smaller footprint and low BOM cost, make the device ideal for today's growing consumer applications."

Package: 16-pin 3mm x 3mm MLF package
Price: Starts at each $1.31 for 1K pieces
Availability: Now
