Texas Instruments UCC2808A-1Q1 Manuals

This document introduces the features of the UCC2808A product, including ESD protection, dual output drive stage configuration, current sense discharge transistor, typical starting current, typical running current, operating frequency, internal soft start, error amplifier, VDD clamping, output drive stage, etc.

This document describes the features and characteristics of the UCC2808A, a family of BiCMOS push-pull, high-speed, low-power, pulse-width modulators. The UCC2808A is qualified for automotive applications and supports customer-specific configuration control and major-change approval. It provides ESD protection exceeding 1500 V per MIL-STD-883, Method 3015, and exceeds 200 V using the Machine Model (C = 200 pF, R = 0). The UCC2808A features dual output drive stages in a push-pull configuration, a current sense discharge transistor to improve dynamic response, a typical starting current of 130 µA, and a typical run current of 1 mA. It can operate up to 1 MHz and has internal soft start. The on-chip error amplifier has a 2-MHz gain bandwidth product, and on-chip VDD clamping is provided. The output drive stages are capable of 500-mA peak-source current and 1-A peak-sink current.
