Description

DATASHEET LM5642 /LM5642X High Voltage, Dual Synchronous Buck Converter with Oscillator . SYNC = LOW: Free running at 200 kHz for LM5642 , and at 375kHz for AN-1292 LM5642 Evaluation Board. 1. Introduction. The LM5642 IC is a dual channel, current-mode, synchronous buck converter controller. It can handle. cost-effectiveness of power management ICs such as the LM5030 push-pull controller and the LM5642 two-channel current-mode synchronous buck controller. LM5642 /X, LM3753/54. LM2743, LM25116,. LM3753/54, LM5642 /X. 4. Legend. Non Sync Sync Reg Power Module Controller BOLD = WEBENCH LM5642 typical application circuit. Product Highlight: Highly efficient POL controller for distributed power architectures. LP3884x Dual-rail low 0.56V output,
