The R1202L721A-TR is a CMOS-based PWM step-up DC/DC converter IC manufactured by Nisshinbo Micro Devices. It is designed for high-efficiency power conversion with a low supply current of typically 800µA and a standby current of a maximum of 5µA.
Key electrical specifications include an input voltage range of 2.3V to 5.5V (for A/B versions), a feedback voltage of 1.0V ±15mV (for A/B versions), and a typical oscillator frequency of 1.2MHz. It offers a maximum duty cycle of typically 91% and an Lx current limit selectable from 350mA or 700mA. Protection features include under-voltage lockout (UVLO), over-voltage protection (OVP), and thermal shutdown.
This converter is available in a DFN1616-6B package, suitable for surface mount applications. The R1202x series includes versions optimized for constant-voltage power supply (R1202xxxxA/B) and for driving serial white LEDs with constant current (R1202xxxxD). The R1202xxxxA version includes a built-in auto-discharge function.
The R1202L721A-TR is designed for applications requiring efficient voltage step-up conversion. Its integrated features and compact package make it suitable for various electronic designs where space and power efficiency are critical.
