Texas Instruments TPSM82902 Buck Converter is a highly efficient, small, easy-to-use, and flexible synchronous step-down DC-DC converter in a MicroSiP package. The TPSM82902 offers a selectable switching frequency of 2.5MHz or 1.0MHz, allowing the use of small components and fast transient response.
With the DCS-Control topology, the TI TPSM82902 buck converter supports high VOUT accuracy of ±1%. The device’s wide input voltage range of 3V to 17V enables a variety of nominal inputs, like 12V supply rails, single-cell or multi-cell Li-Ion, and 5V or 3.3V rails. The TPSM82902 automatically enters power save mode (if auto PFM/PWM is selected) at light loads to maintain high efficiency. Additionally, to supply high efficiency at tiny loads, the device has a low typical quiescent current of 4µA. AEE, if enabled, delivers high efficiency across VIN, VOUT, and load current. The TPSM82902 includes a MODE/Smart-CONF input to set the internal/external divider, switching frequency, output voltage discharge, and automatic power save mode or forced PWM operation.
The TPSM82902 is housed in a small 11-pin MicroSiP package measuring 3.0mm x 2.8mm x 1.6mm with an integrated 1μH inductor.
