... Detailed Description Functional Description The AS1302 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-switching to achieve the highest possible efficiency. The regulation of the ...

... Datasheet - Switch Configuration The AS1302 has nine built-in power switches in the shape of two coupled H-bridge topologies. The system features 1:2 and 2:3 operation modes as well as a 1:1 operation where the input is directly connected to the output. ...

... An internal hysteresis of 300mV prevents ringing during startup. If the input voltage increases to 2.8V (typ) again after such a condition the device turns-on automatically. Shutdown Mode The AS1302 enters low-power shutdown mode when EN is set to logic low. In shutdown the charge-pump action is halted, the output is completely disconnected from the input and V Short-Circuit Protection Short-circuit protection prevents damage to the device if the output is shorted to ground ...

... AS1302 Datasheet - Application Information External Component Selection The high internal oscillator frequency of 1.2MHz permits the use of small capacitors for both, the flying capacitors and the output capacitors. For any given load the value of the flying- and output capacitors as well as their ESR are affecting the output voltage performance. In general, the capacitor’ ...

... Layout Consideration To achieve the best performance of the AS1302 a careful board layout is necessary to reduce the impact of the high switching frequency and the high transient currents which are produced by the device. For a proper regulation under all conditions a true ground plane and short connections to all external capacitors are needed. ...
