Fairchild Semiconductor FAN21 TinyBuck™ Synchronous Buck Regulators
Fairchild Semiconductor FAN21 TinyBuck™ integrated synchronous buck regulators
contain synchronous MOSFETs and a controller/driver with optimized
interconnects in one package, enabling designers to solve high-current
requirements in a small area with minimal external components. The
devices boast a peak efficiency of over 95% and wide input and output
voltage ranges. FAN21 TinyBuck regulators provide programmable
frequency operation of 200KHz to 600KHz and include external
compensation, programmable switching frequency, and current limit
features that allow design optimization and flexibility. These Fairchild Semiconductor TinyBuck synchronous buck regulators
also offer a summing current mode modulator that uses lossless current
sensing for current feedback and over-current protection.
Fairchild Semiconductor FXLA104 / FXLA108 Automatic Direction Translators
The Fairchild Semiconductor FXLA104 and FXLA108 automatic direction voltage translators provide built-in automatic direction control that allows the translator to sense and control the direction data should flow without a direction control pin. These Fairchild Semiconductor configurable dual-voltage supply translators work for both uni-directional and bi-directional voltage translation between two logic levels and allow translation between voltages as high as 3.6V to as low as 1.1V. The Fairchild Semiconductor FXLA104 is a 4-bit translator ideal for designs needing four bits, such as cell phones. The FXLA108 is an 8-bit translator optimal for notebook applications. Both translators have a capacitance of less than 10pf, easing current flow and lowering power consumption.
Fairchild Semiconductor Primary Side Regulation PWM Controllers
Fairchild Semiconductor primary side regulation pulse-width modulation (PWM) controllers address a critical need in the high brightness LED market by simplifying design, reducing board space, and providing performance advantages. The Fairchild Semiconductor FSEZ1016A is an EZSWITCH™ that integrates a PSR PWM controller with a power MOSFET. The Fairchild Semiconductor FAN100 is a PSR PWM controller. These primary side regulation PWM controllers achieve the most accurate constant current through their built-in proprietary TRUECURRENT™ technology and tight constant voltage without using secondary-side feedback circuitry.
Fairchild Semiconductor FXM2IC102 Voltage Translator
Fairchild Semiconductor´s FXM2IC102 I2C interface voltage translator provides bi-directional interface between any two levels from 1.65V to 5.5V. The device accommodates standard-mode and fast-mode I2C bus devices, provides non-preferential power-up of either Vcc, and features auto-sense capability that allows either port to sense an input signal and transfer it as an output signal to the other port.
