TI's 6-MHz buck converter, TPS62601, is the smallest 500mA DC/DC solution on the market. It builds extremely thin with 0.6mm height and an ultra-small footprint of 13mm2, making it ideal for applications where space limitations are critical and performance and efficiency are required.

The TPS62601 device is a high-frequency synchronous step-down dc-dc converter optimized for battery-powered portable applications. Intended for low-power applications, the TPS62601 supports up to 500mA load current, and allows the use of low cost chip inductor and capacitors.

With a wide input voltage range of 2.3V to 5.5V, the device supports applications powered by Li-Ion batteries with extended voltage range. Different fixed voltage output versions are available from 1V to 2.5V.

The TPS62601 operates at a regulated 6-MHz switching frequency and enters the power-save mode operation at light load currents to maintain high efficiency over the entire load current range.

The PFM mode extends the battery life by reducing the quiescent current to 30mA (typ) during light load and standby operation. For noise-sensitive applications, the device can be forced into fixed frequency PWM mode by pulling the MODE pin high. In the shutdown mode, the current consumption is reduced to less than 1mA.

The TPS62601 is available in a 6-pin chip-scale package (CSP).
