... The AS1301 is a 50mA inductorless boost converter using a double H-bridge charge-pump topology with two external flying capacitors. The AS1301 runs on a 1MHz fixed frequency and is utilized with a low noise regulation scheme to allow usage together with sensitive RF circuitry from the same battery supply. ...

... Functional Description www.datasheet4u.com The AS1301 is a high efficiency and low noise switched capacitor DC/DC converter that is capable of boost operation equipped with two built-in coupled H-bridge type switch configurations. Based on the value of the output voltage the system automatically initiates mode up-switching to achieve the highest possible efficiency. The regulation of the ...

... Switch Configuration The AS1301 has nine built-in power switches in the shape of two coupled H-bridge topologies. The system features 1:2 and 2:3 operation mode as well as an 1:1 operation where the input is directly connected to the output. This feedthrough mode is suitable for input voltages higher than the output voltage ...

... Overload Protection When the output voltage drops about 200mV below battery voltage due to very high load the AS1301 enters overload protection condition. In this condition the output is connected to the input via a current limiting connection. Once the overload is removed, the device enters soft start periode and ramps up to the nominal output voltage ...

... Charge-Pump Capacitor Selection To ensure the required output current and avoid high peak currents the values of the flying capacitors C are very critical. A 120nF capacitor is sufficient for most applications. Dependent on the operation mode the AS1301 alternately charges and discharges the C voltage ripple, the voltage drop caused by the ESR of the flying capacitors affects the maximum available output voltage ...
