This application note explains the calculation of external capacitor value for buck converter IC circuit. Change of capacitance value due to temperature can obtain stable temperature characteristic by ...

This application note covers the steps required in choosing the inductor and to calculate the value used in buck regulator IC circuits. Switching regulators are used in a variety of applications to ...

Texas Instruments’ TPS53915 (Fig. 1), can supply up to 12 A output that is adjustable from 0.6 V to 5.5 V. Its input voltage ranges from 1.5 V to 18 V. A 4.5 V to 25 V VDD input powers an internal 5 V ...

STMicroelectronics is has chosen an isolated buck converter topology for a 10W dc-dc converter that provides a regulated local primary power rail, plus a moderately regulated isolated secondary power ...

The SPI-8010A is a high-efficiency (94%), adjustable-output, 3-A buck converter IC, available in an HSOP16 package with enhanced thermal-dissipation capability. The package's special ground-potential ...

Linear Technology’s LTC3119 is an efficient, monolithic buck-boost converter that operates with inputs from 2.5 to 18 V (Fig. 1), making it well-suited to operate from one- to four-cell Li-ion ...

STMicroelectronics has created a 5W dc-dc buck converter IC that produces a regulated non-isolated output plus one or more transformer-coupled isolated outputs. The isolated secondary voltage is ...

In the last installment of Circuit VR, we walked around a simplified buck converter. The main simplification was using a constant PWM signal. The result is that the output voltage is a fixed fraction ...
