Характеристики

MAX1945REUI+, регулятор напряжения пониж. Ind mMAX28The MAX1945REUI+ is an internal switch step down regulator in 28 pin TSSOP package. The high efficiency PWM switching regulator operates from an input supply range of 2.6V to 5.5V and provides selectable output voltages of 1.8V, 2.5V and adjustable output voltages from 0.8V to 85% of supply voltage. The input voltage can be as low as 2.25V with VCC at 3.3V/5V. The MAX1945R is ideal for onboard post regulation applications. Total output voltage error is less than ±1% over load, line and temperature. The device operates at a selectable fixed frequency (500KHz or 1MHz) or can be synchronized to an external clock (400KHz to 1.2MHz). The high bandwidth of internal error amplifier provides excellent transient response. The MAX1945R has internal dual N channel MOSFETs to lower heat dissipation at heavy loads. It is used in low voltage, high density distributed power supplies, ASIC, CPU and DSP core voltages RAM power supply, base station, telecom & networking equipment power supplies.
