产品概述

描述

The L99LD02 is a two-phase, constant frequency, current mode boost controller able to drive N-channel power MOSFETs. Multi-phase operation is supported by SYNC I/O pin, providing the phase shifted clock signal. The boost controllers of more devices can be stacked, in order to operate in multi-phase for high power applications. Multi-phase operation reduces system filtering capacitance and inductance requirements.
The operating frequency is configurable via SPI between 100kHz and 470kHz. Other features include an internal 10V LDO for the gate drivers, soft-start, device supply option from boost output and pre-configurable operation in Limp Home.
