DESCRIPTION
Relying on simple two-terminal inductors rather than transformers, the MAX742 regulates both outputs independently to within ±4% over all conditions of line voltage, temperature, and load current. Two independent PWM currentmode feedback loops provide tight regulation and operation free from subharmonic noise. Also ripple and noise are easy to filter. The MAX742 provides a regulated output for inputs ranging from 4.2V to 10V (and higher with additional components). External power MOSFETs driven directly from the MAX742 are protected by cycle-by-cycle overcurrent sensing. The MAX742 also features undervoltage lockout, thermal shutdown, and programmable soft-start. If 3W of load power or less is needed, refer to the MAX743 data sheet for a device with internal power MOSFETs.
