    Compensation Made SIMPLE With LM4360x, LM4600x
    PDF, 457 Kb, Archivo publicado: jul 29, 2014
    Compensating a DC-DC buck converter is challenging if the designer is not familiar with the loop control theory. To achieve a stable design under all corner and adverse conditions, the user must properly compensate the regulator. While DC-DC converters with external compensation provide flexibility, they increase complexity. The LM43600/1/2/3 and LM46000/1/2 are a family of Wide VIN, fully-synchro
