LC2452S
Overview
- Wide input voltage range: 4.2V to 16V rectified step-down converter that provides wide
- 2.5A output current
- 2V to 16V input voltage range and 2.5A continuous load current capability. The LC2452S can achieve high efficiency and reduce power loss at light load. In shutdown mode, the Max supply current is about 3μA.
- 0.8V reference voltage
- Low RDS(ON) integrated power MOSFET (120/80mΩ)
- 3μA(Max) shutdown current
- Integrated internal compensation
- High efficiency at light load The LC2452S protection function includes cycle-
- Internal 1ms soft-start Preliminary by-cycle current limit, UVLO and thermal shutdown. Besides, internal soft-start prevents inrush current at fast power-on. This device uses Constant On-Time (COT) control mode which provides fast load transient response. Internal loop compensation function reduces the external compensator components and simplifies the design process. The LC2452S requires a minimum number of readily available standard external components and is available in a SOT23-6 tiny package.
- Cycle-by-cycle current limit
