MAX258 Overview
Key Specifications
Mount Type: Surface Mount
Pins: 8
Max Voltage (typical range): 5.5 V
Min Voltage (typical range): 3 V
Description
The MAX258 is a 500mA, push-pull transformer driver designed to provide a simple solution for isolated power supplies. The IC has an internal oscillator and operates from a single +3.0V to +5.5V supply.
Key Features
- an integrated oscillator driving a pair of n-channel power switches
- Internal circuitry guarantees a fixed 50% duty cycle to prevent DC current flow through the transformer
- The IC operates with up to 500mA of continuous current and features undervoltage lockout and thermal shutdown
- The IC includes a low-current shutdown mode to reduce the overall supply current to less than 5µA (max) when the driver is disabled
- The MAX258 is available in a small 8-pin (2mm x 3mm) TDFN package and is
