1 Introduction

The TPS7H4001-SP is a space-grade, radiation hardened, 7-V, 18-A, synchronous buck, point-of-load (POL) converter, which has been optimized for small designs with high-efficiency operation and integration of the high-side and low-side power MOSFETs into a compact monolithic design. Further space saving is achieved through the use of the configurable switching frequency (0.1 MHz to 1 MHz), which can reduce the output filter lumped components and optimizing the power density (W/in3). The device is offered in a thermally enhanced 34-pin ceramic, dual inline flat-pack package. General device information and test conditions are listed in Table 1-1. For more detailed technical specifications, user guides, and application notes, see the TPS7H4001-SP product page.
