ADP1612/ADP1613 is a 650kHz / 1.3MHz step-up PWM DC-to-DC switching converter. It features adjustable output voltage, minimum input voltage, current limit, soft start, undervoltage lockout, thermal shutdown, etc.
The ADP1612 and ADP1613 are step‑up DC‑to‑DC switching converters with an integrated power switch capable of delivering up to 20 V output, making them suitable for space‑constrained applications such as portable devices and TFT LCD bias supplies. They operate in current‑mode PWM with selectable switching frequencies of 650 kHz or 1.3 MHz and include features such as soft‑start, UVLO, and thermal shutdown.

| Input Voltage (VIN) – ADP1612 | 1.8 V to 5.5 V |
|---|---|
| Maximum Output Voltage | 20 V |
| Switching Frequency Selection | 650 kHz or 1.3 MHz (pin‑selectable) |
| Thermal Shutdown Threshold | 150 °C |
The converters can provide an output voltage as high as 20 V.
Connect the FREQ pin to GND for 650 kHz or to VIN for 1.3 MHz.
Thermal shutdown is triggered at 150 °C.
