Three operating modes can be programmed with the EN pin. EN = Low disables the device. Output and input are isolated in the shutdown mode and the output capacitor is automatically discharged. EN = High lets the device run from the internal oscillator. If an external clock signal is applied to the EN pin, the device is in Sync–Mode and runs synchronized at the frequency of the external clock signal. GND 2 1, 2 Ground IN 7 7 I Supply input. Bypass IN to GND with a capacitor of the same size as CO. LBI 1 — I Low-battery detector input for TPS60200 and TPS60202. A low-battery warning is generated at the LBO pin when the voltage on LBI drops below the threshold of 1.18 V. Connect LBI to GND if the low-battery detector function is not used. For the devices TPS60201 and TPS60203, this pin has to be connected to ground (GND pin). LBO 10 — O Open-drain low-battery detector output for TPS60200 and TPS60202. This pin is pulled low if the voltage on LBI drops below the threshold of 1.18 V. A pullup resistor should be connected between LBO and OUT or any other logic supply rail that is lower than 3.6 V. OUT 5 5 O Regulated 3.3-V power output. Bypass OUT to GND with the output filter capacitor CO. PG — 10 O Open-drain power-good detector output for TPS60201 and TPS60203. As soon as the voltage on OUT reaches about 90% of it is nominal value this pin goes active high. A pullup resistor should be connected between PG and OUT or any other logic supply rail that is lower than 3.6 V. |
