Description

Jan 13, 2014 Schmitt trigger action on each input with no external components. Hysteresis voltage typically 0.9 V at VDD = 5 V and 2.3 V at VDD =10 V. Noise immunity greater than 50 % of. VDD ( typ.) No limit on input rise and fall times. Quiescent current specified up to 20 V. Standardized symmetrical output. UC3844B, UC3845B,. UC2844B, UC2845B. High Performance. Current Mode Controllers. The UC3844B, UC3845B series are high performance fixed frequency current mode controllers. They are specifically designed for Off Line and dc dc converter applications offering the designer a cost effective solution with minimal The TL494 device contains two error amplifiers, an on-chip adjustable oscillator, a dead-time control. (DTC) comparator, a pulse-steering control flip-flop, a. 5-V, 5 %-precision regulator, and output-control circuits. The error amplifiers exhibit a common-mode voltage range from 0.3 V to VCC 2 V. The dead-time. Apr 29, 2010 The ISL6236 dual step-down, switch-mode power-supply. (SMPS) controller generates logic-supply voltages in battery-powered systems. The ISL6236 include two pulse-width modulation (PWM) controllers, 5V/3.3V and. 1.5V/1.05V. The output of SMPS1 can also be adjusted from. 0.7V to 5.5V. The
