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 : Precision Voltage-to-Frequency Converters

Description
The LMx31 family of voltage-to-frequency converters are ideally suited for use in simple low-cost circuits for analog-to-digital conversion, precision frequency to-voltage conversion, long-term integration, linear frequency modulation or demodulation, and many other functions. The output when used as a voltage-to-frequency converter is a pulse train at a frequency precisely proportional to the applied input voltage. Thus, it provides all the inherent advantages of the
voltage-to-frequency conversion techniques, and is easy to apply in all standard voltage-to-frequency converter applications.

Description : Micropower Voltage Detector

The MCP111/112 are voltage-detecting devices designed to keep a microcontroller in reset until the
system voltage has stabilized at the appropriate level for reliable system operation.

These devices also operate as protection from brown-out conditions when the system supply voltage drops below the specified threshold voltage level. Eight different trip voltages are available.

Part Name(s) : NJM2405 NJM2405M JRC
Japan Radio Corporation
Description : VOLTAGE DETECTOR

■ GENERAL DESCRIPTION
NJM2405 is a dual comparator, including the high precision reference voltage circuit. Both channels have hystersis pins, so it could provide the hysteretic function for systems.
It has the wide range of operating voltage and works with less current consumption, so that it is suitable for detecting abnormal conditions, to change over to back up memories when the voltage drops off in operation.

■ FEATURES
• Operating Voltage (2.5V to 20V)
• Low Operating Current
• Internal Low Reference Voltage
• Adjustable Hystersis Voltage
• Package Outline DMP8
• Bipolar Technology

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.
