The most common switching-power topology is a buck converter, which efficiently transforms high voltages to low voltages. Figure 1 shows a typical buck converter in which the N-channel MOSFET, Q 1, ...
Milpitas, Calif. – Intersil's Endura ISL6522B is a single-phase dual-mode synchronous-buck PWM controller/driver IC designed to solve start-up problems associated with pre-biased loads such as found ...
Tight foundry capacity has constrained semiconductor supply, with PWM ICs in particularly serious shortages. The IC shortages are delaying shipments of end-market devices that are badly needed to ...
The supply of handset-use power management ICs remains severely tight, prompting the chip suppliers to transition to 12-inch wafer manufacturing, according to industry sources. PWM IC suppliers ...
Pulse width modulation is a form of signal communication that transposes a signal from analog to digital form. Analog signals with changing amplitude and frequency pass through a comparator and are ...
Demand is growing, particularly in emerging economies, for high-efficiency three-phase brushless fan motors that can reduce energy consumption and manage fluctuations in power voltage. Such motors ...
PWM or Pulse Width Modulation has generally been regarded as too complicated for PC fan speed control compared against using rheostats or linear voltage regulators such as the LM317. I present here a ...
7) Custom designed PWM IC with SCD – Noctua’s custom-designed NE-FD1 is a next-generation PWM fan driver IC that integrates Smooth Commutation Drive (SCD) technology for quieter operation and allows ...
The IRU3038 synchronous pulse-width modulation (PWM) controller IC handles the termination-voltage requirements of double-data-rate (DDR) memory arrays. By ...
The A3965 dual full-bridge pulse-width modulation (PWM) motor driver IC incorporates two DMOS H-bridges capable of output currents to ±500 mA. The unit handles motor ...
Vienna, November 30th 2011 – Enlarging its portfolio of premium quality quiet fans, Noctua today announced PWM versions of its renowned NF-P12, NF-B9 and NF-R8 fans. Having received more than hundred ...
