Berekening – IC driver
Diverse handige programma’s om IC driver berekeningen te maken.
MIC3201 HIGH BRIGHTNESS LED DRIVER CURRENT SENSE
MIC3201 is a hysteretic step-down, constant-current, High-Brightness LED (HB LED) driver capable of driving up to four, 1A LEDs. It provides an ideal solution for interior/exterior lighting, architectural and ambient lighting, LED bulbs, and other general illumination applications. The MIC3201 operates with an input voltage range from 6V to 20V. The hysteretic control gives good supply rejection and fast response during load transients and PWM dimming. The high-side current sensing and on-chip current sense amplifier delivers LED current with ±5% accuracy. An external high-side current sense resistor is used to set the output current.
HV9910 UNIVERSAL HIGH BRIGHTNESS LED DRIVER
HV9910 is a PWM high-efficiency LED driver control IC. It allows efficient operation of High Brightness (HB) LEDs from voltage sources ranging from 8VDC up to 450VDC. The HV9910 controls an external MOSFET at fixed switching frequency up to 300kHz. The frequency can be programmed using a single resistor. The LED string is driven at constant current rather than constant voltage, thus providing constant light output and enhanced reliability. The output current can be programmed between a few milliamps and up to more than 1.0Amp.
Despite their small size quite useful programs languages spanish but many units are universal because you can deal hopefully this kind of program on Turkish those are written in the uc384x series ir2153 and mc34063 integrated the basis of calculation of all of the different programs out can be made.
