10 pcs : LT8277RUDCMWPBF - Voltage Regulators - Switching Regulators Multiphase Boost Controller

LT8277 Multiphase Step-Up DC/DC Controllers Analog Devices LT8277 Multiphase Step-Up DC/DC Controllers offer 2-phase constant frequency, current mode boost, and a 3V to 40V wide input voltage range. The SEPIC controllers are designed to drive N-channel power MOSFETs. The 2-phase interleaved function downsizes system filtering capacitance requirements. An internal LDO regulator pulls power from VIN or VOUT to deliver a 5V supply for the gate drivers. The fixed frequency, current-mode architecture results in stable operation over a wide range of supply/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 permit multiple LT8277 devices to perform together, facilitating 4- or 8-phase operation.
