1 Introduction

The TPS7H500x-SP series (consisting of TPS7H5001-SP, TPS7H5002-SP, TPS7H5003-SP, and TPS7H5004- SP) is a family of high speed radiation-hardness-assured PWM controllers. The TPS7H5001-SP is the parent device with only interconnect differences to support the reduction of features for TPS7H5002/3/4-SP. The controllers provide a number of features that are beneficial for the design of DC-DC converter topologies intended for space applications. The controllers have a 0.613 V ±1 % accurate internal reference and configurable switching frequency up to 2 MHz. Each device offers programmable slope compensation and soft-start. The TPS7H500x-SP series can be driven using an external clock through the SYNC pin or by using the internal oscillator at a frequency programmed by the user. The controller family offers the user various options for switching outputs, synchronous rectification capability, dead time (fixed or configurable), leading edge blank time (fixed or configurable), and duty cycle limit. Each device in the TPS7H500x-SP series has a 22-pin CFP package.

Table 1-1 lists general device information and test conditions For more detailed technical specifications, user guides, and application notes, see the TPS7H500x-SP product page.

Each TPS7H500x-SP device has a special set of outputs, configurations, and settings. From device to device, the number of outputs, dead-time and leading edge blank time configurability, and duty cycle limit options can vary. The table below gives a breakdown of each device in the TPS500x-SP series.
