... 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%. 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 is set-up internally in 100mV steps within the range of 1.6V to 4.0V(± ...

... Please be noted that the recommend value above of the CL2 may be changed depending on the input voltage value and setting voltage value. ■OPERATIONAL EXPLANATION The XC9510 series consists of a synchronous step-down DC/DC converter, a high speed LDO voltage regulator, and a voltage detector. Since the LDO voltage regulator is stepped-down from the DC/DC’s output,high efficiency and low noise is possible even at lower output voltages. ...

... The XC9510A to F series are PWM control, while the XC9510H to L series can be automatically switched between PWM control and PWM/PFM control. The PWM of the XC9510A to F series are controlled on a specified frequency from light loads through the heavy loads. Since the frequency is specified, the composition of a noise filter etc. becomes easy. ...

... CE/MODE pin. The input to the CE/MODE pin is a CMOS input and the sink current is 0μA (TYP.). The operation of the XC9510D to F series' voltage detector block will enter into stand-by mode when a high level signal is input to the CE/MODE pin. The voltage regulator block will operate when a middle level signal is input ...

... DC/DC's and the regulator's load if the regulator has load.) 6. When the XC9510H to L series operates in PWM/PFM automatic switching control mode, the reverse current may become quite high around the load current value when synchronous switches to non-synchronous and vise versa (also refer to no ...

... Use of the IC at voltages below the recommended voltage range may lead to instability. 12. This IC and the external components should be used within the stated absolute maximum ratings in order to prevent damage to the device. Since the DC/DC converter and the regulator of the XC9510 series are connected in series, the sum of the output 13. current (ID ...
