The TPS8269xSIP device is a complete 500 mA / 800 mA, DC/DC step-down power supply intended for low-power applications. Included in the package are the switching regulator, inductor and input/output capacitors. No additional components are required to finish the design. The TPS8269xSIP is based on a high-frequency synchronous step-down dc-dc converter optimized for battery-powered portable applications. The MicroSIP™ DC/DC converter operates at a regulated 3-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 23 μA (typical) during light load operation. For noise-sensitive applications, the device has PWM spread spectrum capability providing a lower noise regulated output, as well as low noise at the input. These features, combined with high PSRR and AC load regulation performance, make this device suitable to replace a linear regulator to obtain better power conversion efficiency. The TPS8269xSIP is packaged in a compact (2.9 mm × 2.3 mm) and low profile (1 mm) BGA package suitable for automated assembly by standard surface mount equipment.

NAME | NO. | ||
VOUT | A1 | O | Power output terminal. Apply output load between this terminal and GND. |
VIN | A2, A3 | I | The VIN terminals supply current to the TPS8269xSIP's internal regulator. |
EN | B2 | I | This is the enable terminal of the device. Connecting this terminal to ground forces the converter into shutdown mode. Pulling this terminal to VIN enables the device. This terminal must not be left floating and must be terminated. |
MODE | B1 | I | This is the mode selection terminal of the device. This terminal must not be left floating and must be terminated. |
MODE = LOW: The device is operating in regulated frequency pulse width modulation mode (PWM) at high-load currents and in pulse frequency modulation mode (PFM) at light load currents. | |||
MODE = HIGH: Low-noise mode enabled, regulated frequency PWM operation forced. | |||
GND | C1, C2, C3 | – | Ground terminal. |
