XC9515BB01ZL Overview

2 channel Synchronous Step-Down DC/DC Converter with Manual Reset

XC9515
Series
2 channel Synchronous Step-Down DC/DC Converter with Manual Reset
ETR0706-008
■GENERAL
DESCRIPTION
The XC9515 series consists of 2 channel synchronous step-down DC/DC converters and a voltage detector with delay circuit
built-in. The DC/DC converter block incorporates a P-channel 0.35Ω (TYP.) driver transistor and a synchronous N-channel
0.35Ω (TYP.) switching transistor. By minimizing ON resistance of the built-in transistors, the XC9515 series can deliver
highly efficient and a stable output current up to 800mA. With high switching frequencies of 1MHz, a choice of small inductor
is possible. The series has a built-in UVLO (under-voltage lock-out) function, therefore, the internal P-channel driver
transistor is forced OFF when input voltage becomes 1.8V or lower (for XC9515A, 2.7V or lower). The voltage detector block
can be set delay time freely by connecting an external capacitor. With the manual reset function, the series can output a
reset signal at any time.

Please tell me why the 15V output of the circuit in the attached picture is connected with GND
I would like to ask, in the BPA8505D in the figure below (1), why does the VCC pin output 15V DC pass through capacitor C4 before output? Doesn't the capacitor block DC?(2) Why is VCC connected to the...
