LC2632 Datasheet | LEADCHIP

DESCRIPTION The LC2632 is a fully integrated, synchronous rectified step-down converter that provides wide 4.2V to 28V input voltage range and 2A continuous load current capability. The LC2632 can operate at PFM mode to achieve high efficiency and reduce power loss at light load. In shutdown mode, the Max supply current is about 3μA. The LC2632 protection function includes cycle-bycycle current limit, UVLO and thermal shutdown. Besides, internal soft-start prevents inrush current at fast power-on. This device uses slope pensated current mode control which provides fast load transient response. Internal loop pensation function reduces the external pensator ponents and simplifies the design process. The LC2632 requires a minimum number of readily available standard external ponents and is available in ESOP-8 (Exposed Pad) package and provides good thermal conductance.
