TPSM82850x-Q1 is a family of pin-to-pin compatible, 1A, and 2A, automotive high-efficiency and easy to use synchronous step-down DC/DC power modules with integrated inductors. The devices use a fixed-frequency peak current-mode control topology and are suitable for automotive applications with high power density and ease of use requirements. Low resistance switches allow up to 2A continuous output current at high ambient temperatures. The switching frequency can be fixed at 2.25MHz through pin-strapping or selected from a range of 1.8MHz to 4MHz through a set resistor. The module can also be synchronized to an external clock in the range from 1.8MHz to 4MHz. In PFM/PWM mode, the TPSM82850x-Q1 automatically enters power save mode at light loads to maintain high efficiency across the whole load range. The TPSM82850x-Q1 provides a 1% feedback voltage accuracy in PWM mode which helps design a power supply with high output voltage accuracy. The COMP/FSET pin sets the switching frequency, one out of two loop compensation settings and the SSC function for a wide variety of load conditions
