The TPS62A03 and TPS62A03A are synchronous, step-down, buck DC/DC converters designed for high efficiency and compact design size. The devices integrate switches capable of delivering an output current up to 3A. At medium to heavy loads, the devices operate in pulse width modulation (PWM) mode with 2.2MHz switching frequency. At light load, the TPS62A03 automatically enters power save mode (PSM) maintaining high efficiency over the entire load current range. The TPS62A03A variant of this device operates in PWM mode across the whole load current range with a fixed switching frequency. In shutdown, the current consumption is minimal for both devices.
The TPS62A03 and TPS62A03A provide an adjustable output voltage through an external resistor divider. An internal soft-start circuit limits the inrush current during start-up. Overcurrent protection and thermal shutdown protect device and application under fault conditions. A power good signal indicates that the output voltage is in correct regulation. The devices are available in a SOT563 package. The TPS62A03 and TPS62A03A can upgrade existing TLV62585 based power supply circuits if better efficiency or higher accuracy over a wider temperature range is needed.
