MOSFETs improve 12V-input converter efficiency
Two new 20V HEXFET power MOSFET families from International Rectifier are designed to increase efficiency by up to 4% in 12V-input DC/DC convertors.
IR's new highly-integrated and fully-protected IRS2166D ballast control IC offers designers much of what they need in a small footprint simplifying their design tasks while delivering a high degree of programmability The new IRS2166D integrates PFC, ballast control and half-bridge driver in a compact monolithic IC.
Its PFC circuitry operates in critical conduction mode for a high power factor (PF) of 0.99, low total harmonic distortion (THD) of less than 10 percent, and also precise DC bus regulation within a tolerance of 2.5 percent.
Many of the protection features are programmable including those for half-bridge over-current, dead-time and preheat-time, preheat and run frequencies, and lamp end-of-life.
Other features include protection from failure of the lamp to strike, filament failures, and DC bus under-voltage reset.
Available in 16-lead DIP and SO lead-free packages, the devices provide 50% duty cycle, integrated bootstrap circuitry, a 15.6V Zener diode clamp on VCC, and typical micro-power startup current of 250uA.
IR's new ballast control IC utilises IR's advanced high-voltage IC process which incorporates next-generation high-voltage level-shifting and termination technology to deliver superior electrical over-stress protection and higher field reliability.
