MAX1964 Product details

Description

The MAX1964/MAX1965 power-supply controllers are designed to address cost-sensitive applications demanding voltage sequencing/tracking, such as cable modem consumer premise equipment (CPE), xDSL CPE, and set-top boxes.

Features

voltage sequencing and the MAX1965 features voltage tracking. Both controllers provide a powergood output that monitors all of the output voltages. o 4.5V to 28V Input Voltage Range o Master DC-DC Step-Down Converter: Preset 3.3V or Adjustable (1.236V to 0.75 x VIN) Output Voltage Fixed Frequency (200kHz) PWM Controller No Current-Sense Resistor Adjustable Current Limit 95% Efficient Soft-Start o Two (MAX1964)/Four (MAX1965) Analog Gain Blocks: Positive Analog Blocks Drive Low-Cost PNP Pass Tran.
