TOREX SEMICONDUCTOR XC9510

The XC9510 series consists of a step-down DC/DC converter and a high-speed LDO regulator connected in series with the DC/DC converter's output. The DC/DC converter block incorporates a P-Channel driver transistor and a synchronous N-Channel switching transistor. With an external coil, diode and two capacitors, the XC9510 can deliver output currents up to 800mA at efficiencies over 90%.

GENERAL DESCRIPTION

A voltage detector is also built-in. A highly efficient, low noise output is possible since the regulator is steppeddown further from the DC/DC output. The XC9510 is designed for use with small ceramic capacitors. A choice of three switching frequencies are available, 300 kHz, 600 kHz, and 1.2 MHz. Output voltage settings for the DC/DC and VR are set-up internally in 0.1V steps within the range of 0.9V to 4.0V ( ± 2.0%). For the VD, the range is of 0.9V to 5.0V (± 2.0%). The soft start time of the series is internally set to 5ms. With the builtin U.V.L.O. (Under Voltage Lock Out) function, the internal P-channel driver transistor is forced OFF when input voltage becomes 1.4 V or lower. The operational states of the DC/DC and the regulator blocks can be changed by inputting three kinds of voltage level via the CE/MODE pin. The fu...
