The TPS6240x-Q1 family of devices are synchronous dual step-down DC-DC converters optimized for battery-powered portable applications and automotive systems. They provide two independent output voltage rails powered by rechargeable batteries or standard 3.3-V or 5-V voltage rail.
The EasyScale™ serial interface allows output-voltages modification during operation. The fixed-output-voltage versions, TPS62402-Q1,
TPS62404-Q1, and TPS62405-Q1 support one-pin-controlled simple dynamic voltage scaling for low-power processors.
The TPS6240x-Q1 operates at 2.25-MHz fixed switching frequency and enters the power-save mode operation at light load currents to maintain high efficiency over the entire load-current range. For low-noise applications, one can force the devices into fixed-frequency PWM mode by pulling the MODE/DATA pin high. The shutdown mode reduces the current consumption to 1.2-µA, typical. The devices allow the use of small inductors and capacitors to achieve a small solution size.
