Most switch-mode power supplies rely on a PWM (pulse-width-modulated) output that is controlled via voltage feedback. A 555-timer IC can inexpensively perform PWM. The circuit in Figure 1 shows how to ...
The LT3688 dual, 800-mA, 36V input step-down switching regulator integrates a dual power-on reset and a watchdog timer. The device resides in a 4 mm x 4 mm QFN-24 or thermally enhanced TSSOP–24 ...
This application note describes a method for using the timer (on-chip peripheral) of Z8 Encore! and Z8 Encore! XP family of microcontrollers. This document contains sample codes (in C and assembly ...
