MAX743CPE+

Voltage Regulators - DC DC Switching Regulators Overview

The MAX743CPE+ is a dual-output PWM switch-mode regulator housed in a 16-pin PDIP package. It operates with an input voltage range of 4.2 V to 6 V and delivers a maximum output current of 2 A at a switching frequency of 200 kHz. The device provides two programmable outputs, supporting positive and negative dual-rail configurations such as ±12 V or ±15 V. It utilizes boost and buck-boost topologies to achieve efficient voltage conversion within an operating temperature range of 0°C to +70°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'C' indicates the commercial temperature grade (0°C to +70°C) rather than industrial variants. Confirm the 'P' designation corresponds to the 16-pin DIP package for through-hole mounting. Ensure RoHS compliance documentation matches the '+'' suffix requirement for lead-free assembly processes.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a single-cell lithium battery or similar low-voltage source must generate symmetric dual rails. The 2 A switch current rating supports moderate load requirements without external pass transistors. Consider thermal management strategies due to the inherent conduction losses in the PDIP package during continuous operation.
