TS2507
0.5A / 330KHz PWM Buck Controller
4/9
Version: A07
Function Descriptions
PWM Control
The TS2507 integrates Pulse-Width-Modulation (PWM) control circuit into a single chip. the pulse width varies in a
range from 0 to 100%, according to the load current. The ripple voltage produced by the switching can easily be
removed through a filter because the switching frequency remains constant. Therefore, these controllers provide a
low-ripple power over broad ranges of input voltage and load current.
RDS(ON) Current Limiting
The current limit threshold is setting by the external resistor (R3) connecting from VCC supply to OCSET pin. The
internal 110uA sink current crossing the resistor sets the voltage at pin of OCSET. When the PWM voltage is less than
the voltage at OCSET, an over-current condition is triggered. Please refer to the formula for setting the current limit
value
(Normally, The ISW(MAX) setting more than IOUT 1A)
Example: ISW=(110uA * 1.8k + 0.11) / 50mΩ (TSM9435CS) = 6.16A
Setting the Output Voltage
Application circuit item shows the basic application circuit with TS2507 adjustable output version. The external resistor
sets the output voltage according to the following equation:

Input Capacitor Selection
The input capacitor reduces the surge current drawn from the input and switching noise from the device. The input
capacitor impedance at the switching frequency shall be less than input source impedance to prevent high frequency
switching current passing to the input. A low ESR input capacitor sized for maximum RMS current must be used.
The capacitor voltage rating should be at least 1.5 times greater than the input voltage, and often much higher voltage
ratings are needed to satisfy.
Output Capacitor Selection
The output capacitor is required to keep the output voltage ripple small and to ensure regulation loop stability. The
output capacitor must have low impedance at the switching frequency. A low ESR capacitor sized for maximum RMS
current must be used. the low ESR requirements needed for low output ripple voltage. The capacitor voltage rating
should be at least 1.5 times greater than the input voltage, and often much higher voltage ratings are needed to satisfy.
