The STEVAL-TDR001V1 is a two-stage RF power amplifier that includes a low pass output filter for harmonics rejection specifically designed for portable two-way UHF radio communication. Its features include excellent thermal stability, frequency range of 380-512 MHz, supply voltage of 7.2 V, output power of 4 W, current less than 1.6 A, input power less than 10 dBm, harmonics level less than -70 dBc, load mismatch of 20:1, maximum VAPC of 5 V, BEO-free amplifier, and RoHS compliance.

The MM54C914-MM74C914 is a monolithic CMOS Hex Schmitt trigger with a special input protection scheme. This scheme allows the input voltage levels to exceed VCC or ground by at least 10V (VCC ≤ 25V to GND ≥ 25V), which is valuable for applications involving voltage level shifting or mismatched power supplies. The positive and negative-going threshold voltages, VTa and VTb, show low variation with respect to temperature (typ 0.0005V/°C at VCC = 10V), and the hysteresis, VTa - VTb ≥ 0.2 VCC, is guaranteed.

This document introduces a monolithic voltage regulator module for supplying DDR2/3 memory and chipset in ultra-mobile PC and real estate portable systems.

The STEVAL-ILB004V1 demonstration board is an electronic ballast that adds “intelligence” to ballast circuits, thanks to the use of a microcontroller. It can drive many different lamp groups and is capable of recognizing T5-type fluorescent lamps with power ratings of 24W, 39W, 54W, and 80W. The board consists of a boost converter (power factor controller) and an inverter in a half-bridge configuration. Both stages are controlled by the ST7LIT19BF1 microcontroller, which provides signals to the L6382D5 power management unit and the STP5NK60Z power MOSFET. After tube recognition, the system sets the parameters to drive the lamp correctly.
