Texas Instruments LP87745 PMIC

Texas Instruments LP87745 Power Management Integrated Circuit (PMIC) is designed to meet the power management requirements of the IWR MMICs in various industrial radar applications. This IC includes a three step-down converter, a 5V boost converter, and 1.8V/3.3V LDO; the LDO is powered by boost and designed for xWR I/O supply. The LP87745 PMIC supports 4.4MHz, 8.8MHz, and 17.6MHz programmable switching frequency range. This PMIC features high switching frequency and low noise across a wide frequency range that enables an LDO-free to-power solution with minimal or no passive filtering. The high switching frequency enhances thermals and transient settling for the MMIC RF rails. The LP87745 PMIC forces the switching clock into PWM mode for optimal RF performance and can also be synchronized to an external clock. This IC supports remote voltage sensing to compensate for IR drop between the regulator output and the Point-Of-Load (POL), improving the output voltage’s accuracy.
