Torex XC9502Series 2ch.Step-Up/Down DC/DC Controller ICs Manual
The XC9502 series is a PWM controlled, PWM/PFM automatic switching controlled, multi-functional, 2 channel step-up and down DC/DC controller ICs. It has a standard voltage supply internal of 0.9V, and the output 1 voltage (step-up DC/DC controller) can be set freely within a range of 1.5V to 30V using externally connected components. The output 2 (step-down DC/DC controller) has a built-in 0.9V reference voltage (accuracy ± 2%), and can be set from 0.9V to 6.0V using external components. With a switching frequency of 180kHz, the size of the external components can be reduced. Switching frequencies of 300kHz and 500kHz are also available as custom-designed products. The control of the XC9502 series can be switched between PWM control and PWM/PFM automatic switching control using external signals. When automatic switching is selected, the control switches from PWM to PFM during light loads, and the series is highly efficient from light loads through to large output currents. Noise is easily reduced with PWM control as the frequency is fixed. The series provides freedom of control selection so that control suited to the application can be selected. The soft-start time is internally set to 10msec (Output1) and offers protection against in-rush currents when the power is switched, preventing voltage overshoot.

Torex XCM526Series 3A 16VDriver Transistor Built-In Step-Down DC/DC Converter Manual
The XCM526 series is a multi-module IC which includes a step-down DC/DC controller IC and P-channel power MOSFET. The IC enables a high efficiency, stable power supply with an output current up to 3A. Low ESR electrolytic capacitors such as an OS-CON aluminum solid capacitor, a tantalum Neo capacitor can be used as an output capacitor. In case of using a ceramic capacitor, RSENSE is needed to be placed on. The XCM526 series has a 0.9V (±1.5%) reference voltage, and using externally connected resistors, the output voltage can be set freely. With an internal switching frequency of 500kHz and 1.0MHz, small external components can also be used. The XCM526A has a fixed PWM control for low output voltage ripple, and the XCM526B has a PWM/PFM control, which automatically switches from PWM to PFM during light loads and high efficiencies can be achieved over a wide range of load conditions. As for the soft-start time, there are two types, one is internally set to 4ms and the other can be externally set-up. With the built-in UVLO (Under Voltage Lock Out) function, the internal P-channel driver transistor is forced OFF when input voltage becomes 2.3V (TYP.) or lower.
