Description : Simple Solution for Dynamically Programming the Output Voltage of DC-DC Converters

INTRODUCTION 
Figure 1 shows a typical dc-to-dc converter configuration. As in many PWM controllers, the non-inverting input of the voltage feedback error amplifier is internally connected to the reference voltage, Vr. The output voltage of the converter is set by a resistor divider network R1 and R2. This configuration enables a fixed output voltage that is equal to or greater than the reference voltage. But in many power conversion designs, it is useful to vary the output to a value lower than the reference voltage and to dynamically adjust the output voltage.

Description : LOW CONSUMPTION VOLTAGE AND CURRENT CONTROLLER FOR BATTERY CHARGERS AND ADAPTORS

DESCRIPTION
TSM1012 is a highly integrated solution for SMPS applications requiring CV (constant voltage) and
CC (constant current) mode. TSM1012 integrates one voltage reference and two operational amplifiers (with ORed outputs - common collectors). The voltage reference combined with one operational amplifier makes it an ideal voltage controller. The other operational, combined with few external resistors and the voltage reference, can be used as a current limiter.

Part Name(s) : TDA8574 TDA8574T TDA8574T/N1 Philips
PhilipsPhilips
Description : Class-H high-output voltage level line driver

GENERAL DESCRIPTION
The TDA8574(T) is a two channel class-H high-output voltage line driver for use in car audio applications. The line driver behaves as a non-inverting amplifier with a gain of 8 dB and a single-ended output. Due to the class-H voltage lifting principle the voltage swing over the load is more than the supply voltage. With a supply voltage of 9 V the output voltage swing over the load will be 14 V (peak-to-peak).

FEATURES
• Output voltage swing larger than supply voltage
• High supply voltage ripple rejection
• Low distortion
• Low noise
• ESD protected on all pins.
