MC33466 Datasheet Fixed Frequency Pwm Micropower DC-to-dc Converter

Manufacturer: Motorola Semiconductor (now NXP Semiconductors)

Overview: .. Order this document by MC33466/D MC33466 Fixed Frequency PWM Micropower DC-to-DC Converter The MC33466 series are micropower switching voltage regulators, specifically designed for handheld and laptop applications, to provide regulated output voltages using a minimum of external parts. A wide choice of output voltages are available. These devices feature a very low quiescent bias current of 15 µA typical.

Key Features

  • a highly accurate voltage reference, an oscillator, a pulse width modulation (PWM) controller, a driver transistor (Lx), an error amplifier and feedback resistive divider. The MC33466H.
  • XXLT1 is identical to the MC33466H.
  • XXJT1, except that a drive pin (EXT) for an external transistor is provided. Due to the low bias current specifications, these devices are ideally suited for battery powered computer, consumer, and industrial equipment where an extension of useful battery life is.
