SGM41283 - 70V Boost Converter

General Description

The SGM41283 is a high voltage non-synchronous Boost converter which integrates a 70V, 600mΩ, N-channel power FET and is capable of up to 1.1A switch current limit.

The Boost converter adopts the fix frequency of 850kHz (TYP) peak current mode control for voltage regulation.

Key Features

  • such as Boost over-current protection, thermal shutdown, and APD current limit adjustment to protect the APD from optical power transients. The SGM41283 is available in a Green TQFN-3×3-16L package. It operates over an ambient temperature range of -40℃ to +125℃.

SGM41283 70V Boost Converter with APD Current Monitor GENERAL DESCRIPTION The SGM41283 is a high voltage non-synchronous Boost converter which integrates a 70V, 600mΩ, N-channel power FET and is capable of up to 1.1A switch current limit. The Boost converter adopts the fix frequency of 850kHz (TYP) peak current mode control for voltage regulation. In addition, the SGM41283 integrates accurate current mirror with two selectable ratios of 10:1 and 2:1 for APD current monitoring. The SGM41283 integrates various protection features such as Boost over-current protection, thermal shutdown, and APD current limit adjustment to protect the APD from optical power transients. The SGM41283 is available in a Green TQFN-3×3-16L package. It operates over an ambient temperature range of -40℃ to +125℃.
