Techcode TD6821

The TD6821 are high-efficiency 1.5MHz synchronous step-down DC-DC regulator ICs capable of delivering up to 1.5A output currents, respectively. The TD6821 operates over a wide input voltage range from 3V to 5.5V and integrate main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss.

GENERAL DESCRIPTION

FEATURES

z low Rds(on) for internal switches (top/bottom): z 3-5.5V input voltage range z 1.5MHz switching frequency minimizes the external components z Internal softstart limits the inrush current z 100% dropout operation z Compact and thermally enhanced package: SOP8-PP Low output voltage ripple and small external inductor and capacitor sizes are achieved with 1.5MHz switching frequency.
