Bottom View of PWP Package, Showing the Thermal Pad Thermal Pad AVAILABLE OPTIONS PACKAGE TSSOP† (PWP) TPS60100PWP † This package is available taped and reeled. To order this packaging option, add an R suffix to the part number (e.g., TPS60100PWPR). Terminal Functions TERMINAL I/O DESCRIPTION NAME NO. I/O DESCRIPTION 3V8 19 I Mode selection. When 3V8 is logic low the charge pump operates in the regulated 3.3-V mode. When 3V8 is connected to IN the regulator operates in preregulated 3.8-V mode. C1+ 6 Positive terminal of the charge-pump capacitor C1F C1− 8 Negative terminal of the charge-pump capacitor C1F C2+ 15 Positive terminal of the charge-pump capacitor C2F C2− 13 Negative terminal of the charge-pump capacitor C2F COM 18 I Mode selection. When COM is logic low the charge pump operates in push-pull mode to minimize output ripple. When COM is connected to IN the regulator operates in single-ended mode requiring only one flying capacitor. ENABLE 3 I ENABLE input. The device turns off, the output disconnects from the input, and the supply current decreases to 0.05 µA when ENABLE is a logic low. ENABLE High may only be applied when VIN is inside the recommended operating range. FB 4 I FEEDBACK input. Connect FB to OUT as close to the load as possible to achieve best regulation. Resistive divider is on chip to match internal reference voltage of 1.22 V. GND 1, 20 GROUND. Analog ground for internal reference and control circuitry. Connect to PGND through a short trace. IN 7, 14 I Supply input. Connect to an input supply in the 1.8-V to 3.6-V range. Bypass IN to GND with a (CO/2) µF capacitor. Connect both INs through a short trace. OUT 5, 16 O Regulated power output. Connect both OUTs through a short trace and bypass OUT to GND with the output filter capacitor CO. VO = 3.3 V when 3V8 = low and VO = 3.8 V when 3V8 = high. PGND 9−12 PGND power ground. Charge-pump current flows through this pin. Connect all PGNDs together. SKIP 17 I Mode selection. When SKIP is logic low, the charge pump operates in constant-frequency mode. Output ripple and noise are minimized in this mode. When SKIP is connect to IN, the device operates in pulse skip mode. Quiescent current is lowest in this mode. SYNC 2 I Selection for external clock signal. Connect to GND to use the internally generated clock signal. Connect to IN for external synchronization. In this case, the clock signal needs to be fed through 3V8 and the device operates in the regulated 3.3-V mode. |
