Diodes Inc. 1.5MHz Step Up DC/DC Converter SOT-23 SMD
1.5MHz step-up DC/DC converter by Diodes Inc. SOT-23-5 SMD, 2.6-16V input, adjustable output up to 29V. Ideal for LCD bias & LED drivers.
This 1.5MHz Step Up DC/DC Converter from Diodes Inc. is a constant frequency, current mode PWM, inductor-based boost converter. Operating at a high frequency of 1.5MHz, it allows the use of small, low-profile inductors, making it highly suitable for space-constrained electronic designs.
The device features built-in overvoltage protection (OVP), initiating shutdown mode when the output voltage exceeds the 29V threshold. Additionally, an integrated soft-start function reduces inrush current during startup, ensuring smooth and reliable operation. Designed for efficiency, it utilises a low ESR ceramic output capacitor and delivers up to 81% efficiency.
With an input voltage range of 2.6V to 16V and an adjustable output reaching up to 29V, this converter supports a maximum output current of 500mA. It boasts a maximum duty cycle of 90% and a switching frequency ranging from 1.1 to 1.9MHz.
Housed in a compact SOT-23-5 SMD package, this surface-mount device is optimised for modern electronics. The operating temperature ranges from -40°C to +85°C, making it suitable for demanding environments. Product dimensions are 43 mm x 33 mm x 15 mm, with a weight of 0.001 grams.
