DESCRIPTION
The LT ®1339 is a high power synchronous current mode switching
regulator controller.
The IC drives dual N-channel MOSFETs to create a single IC solution for high power DC/DC converters in applications up to 60V.
The LT1339 incorporates programmable average current limiting, allowing accurate limiting of DC load current independent of inductor ripple current.
The IC also incorporates user-adjustable slope compensation for minimization of magnetics at duty cycles up to 90%.
The LT1339 timing oscillator operating frequency is programmable and can be synchronized up to 150kHz.
Minimum off-time operation provides main swit...
