BCT12569A数据手册Broadchip中文资料规格书

描述 Description

The BCT12569A is a high efficiency synchronous DC-DC step-down converter. Its input voltage range is from 2.7V to 6.0V .The Adaptive Constant-On-time (ACOT) operation with internal compensation allows the transient response to be optimized over a wide range of loads and output capacitors.

The internal synchronous switch increases efficiency and eliminates the need for external Schottky diode. At shutdown mode, the input supply current is less than 1μA.

The BCT12569A integrates Valley current limit , under voltage protection and thermal protection.

The BCT12569A is available in a SOT563 package, which provides a compact solution with minimal external components.
