VOLTAGE - MODE PWM CONTROLLERS

DESCRIPTION The LX1681/1682 are monolithic, pulsewidth modulator controller ICs. They are designed to implement a flexible, low cost buck (step-down) regulator supply with minimal external components. The LX1681 is a non-synchronous controller; the LX1682 has a synchronous driver for higher effi

125mA, Frequency-Selectable, Switched-Capacitor Voltage Converters

General Description The MAX1680/MAX1681 inductorless switched-capacitor voltage converters either invert an input voltage of +2.0V to +5.5V or double it while supplying up to 125mA output current. They have a selectable-frequency option that allows the use of small capacitors: 4.7µF (MAX1680), 1µ
