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.

Part Name(s) : TSM1012 TSM1012AI TSM1012I ST-Microelectronics
ST-MicroelectronicsST-Microelectronics
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) : LM337SP ST-Microelectronics
ST-MicroelectronicsST-Microelectronics
Description : THREE-TERMINAL ADJUSTABLE NEGATIVE VOLTAGE REGULATORS

The LM337 series are adjustable 3-terminal negative voltage regulators capable of supplying in excess -1.5 A over a -1.2 to -37 V output voltage range. They are exceptionally easy to use and require only two external resistors to set the output voltage. Further, both line and load regulation are better than standard fixed regulators.
