Regulated 5-V High-Power Low-Noise Charge Pump DC/DC Converter
The TPS60111 Step-up regulated Charge Pump generates a 5-V 4% output voltage from a 2.7-V to 5.4-V input voltage (three alkaline, NiCd, or NiMH batteries; or, one lithium or lithium ion battery). Output current is 150 mA from a 3-V input. Only four external capacitors are needed to build a complete low-noise DC/DC converter. The push-pull operating mode of two single-ended Charge Pumps assures the low output voltage ripple as current is continuously transferred to the output. From a 3-V input, the TPS60111 CAN start into full load with loads as low as 33 .
The TPS60111 features either constant frequency mode to minimize noise and output voltage ripple or the power-saving pulse-skip mode to extend battery life at light loads. The TPS60111 switching frequency is 300 kHz. The Logic shutdown function reduces the supply current to 1-uA (max) and disconnects the load from the input. Special current-control circuitry prevents excessive current from being drawn from the battery during start-up. This DC/DC converter requires no inductors and has low EMI It is available in the small 20-pin TSSOP PowerPADTM package (PWP).
