LT8277RUDCMWPBF规格书详情
DESCRIPTION
The LT8277 is a 2-phase constant frequency, current
mode boost and SEPIC controller that drives N-channel
power MOSFETs. The 2-phase interleaved operation
reduces system filtering capacitance requirements. An
internal LDO regulator draws power from VIN or VOUT to
provide a 5V supply for the gate drivers. The fixed
frequency, current-mode architecture results in stable
operation over a wide range of supply and output
voltages. The operating frequency of the LT8277 can be
set over a 100kHz to 2MHz range with an external
resistor or can be synchronized to an external clock
using the SYNC pin. The CLKOUT and SYNC pins allow
multiple LT8277 devices to work together, enabling 4- or
8-phase operation.
