Techcode TD8215
The TD8215 is a single PWM, step‐up DC‐DC controller with low operating voltage application integrating softstart and short circuit detection function. The oscillator switching frequency on chip can be operated by terminating OSC pin to connect capacitor and resistor for adjustable operating frequency. The TD8215 is available in a Pb‐free, SOP‐8 and TSSOP‐8package.| Part No. | TD8215 |

GENERAL DESCRIPTION
FEATURES
Soft‐start is adjusted with the external capacitor, which sets the input current ramp. Besides, the external compensation FB pin will apply the flexibility in the dynamic loop status, which allows using small and low equivalent series resistance (ESR) ceramic output capacitors.● 2.5 to 5.5V Input Voltage Range
● Adjustable Frequency: Maximum 1MHZ
● Incorporates Soft‐Start Function
● Built‐in Short‐Circuit Detection Circuit (SCP)
● Low Operating Current: Maximum to 1mA
● Low Shutdown Current: Maximum to 1µA
● Under‐Voltage Lockout
● Package: SOP‐8 and TSSOP‐8
● Lead Free and Green Devices Available (RoHS Compliant)
