TD8202 Datasheet PDF

Techcode TD8202

The TD8202A/B/C is a current-mode and fixed frequency boost converter with an integrated N-FET to drive up to 8 white LEDs in series. The series connection allows the LED current to be identical for uniform brightness. Its low on-resistance of NFET and feedback voltage reduce power loss and achieve high efficiency.

GENERAL DESCRIPTION

FEATURES

Fast 1MHz current-mode PWM operation is available for input and output capacitors and a small inductor while minimizing ripple on the input supply. The OVP pin monitors the output voltage and stops switching if exceeds the over-voltage threshold. An internal softstart circuit eliminates the inrush current during start-up. The TD8202A/B/C also integrates under-voltage lockout, over-temperature protection, and current-limit circuits. The TD8202/A/B/C is available in a SOT-23-6 packages. z Wide Input Voltage from 2.7V to 6V z 0.25V Reference Voltage z Fixed 1MHz Switching Frequency z High Efficiency up to 87% z 100Hz to 100kHz PWM Brightness Control Frequency z Open‐LED Protection z Under‐Voltage Lockout Protection z Over‐Temperature Protection z <1mA Quiescent Current Dduring Shutdown z SOT‐23‐6 Packages z Lead Free and Green Devices Available z (RoHS Compliant)
