Highly integrated 8A power supply solution

ISM6401A

Description

The ISM6401A power module is a highly integrated 8A power solution that employs a routable lead frame technology to enhance thermal performance, miniaturization, and low EMI. The ISM6401A power module minimizes the use of external components and provides a simplified output inductor design. It includes excellent power, pre-bias startup, and complete protection features such as OCP, NOCP, OVP, UVP, and OTP. The ISM6401A is an outstanding device for powering various load point applications. The module integrates a 5V LDO internally, which can better adapt to single-input power supply application conditions. The differential sense feedback and the use of an internal feedback reference voltage of 0.6V enable the module to achieve an output voltage accuracy within ±1% over the entire operating temperature range, providing excellent line and load regulation. Additionally, it employs the TCOT™ algorithm to enhance the transient response. The internal ramp compensation design enables the use of all MLCC output capacitors, thereby saving space and cost.
