n 24-Lead Narrow SSOP Package
n 5mm Г— 5mm QFN Package with 0.65mm Lead Pitch
n 24-Lead Thermally Enhanced TSSOP Package The LTCВ®3862-2 is a two-phase constant frequency, current
mode boost and SEPIC controller that drives N-channel
power MOSFETs. Two-phase operation reduces system
filtering capacitance and inductance requirements. n The operating frequency can be set with an external resistor …
