Description

General part information

TPS61100 Series

The TPS6110x devices provide a complete power supply solution for products powered by either one or two Alkaline, NiCd, or NiMH battery cells. The converter generates two stable output voltages that are either adjusted by an external resistor divider or fixed internally on the chip. It stays in operation with supply voltages down to 0.8 V. The implemented boost converter is based on a fixed frequency, pulse-width-modulation (PWM) controller using a synchronous rectifier to obtain maximum efficiency.

The maximum peak current in the boost switch is limited to a value of 1800 mA.

The converter can be disabled to minimize battery drain. During shutdown, the load is completely disconnected from the battery. An auto discharge function allows discharging the output capacitors during shutdown mode. This is especially useful in microcontroller applications where the microcontroller or microprocessor should not remain active due to the stored voltage on the output capacitors. Programming the ADEN-pin disables this feature. A low-EMI mode is implemented to reduce ringing and in effect lower radiated electromagnetic energy when the converter enters the discontinuous conduction mode. A power good output at the boost stage provides additional control of cascaded power supply components.
