BD83850GWL-E2

Special Purpose Regulators Overview

The BD83850GWL-E2 is a switching regulator designed for TFT-LCD displays, featuring boost and inverting output power supply capabilities. It operates within an input voltage range of 2.5V to 4.5V and provides a regulated output voltage of approximately 5V with a maximum output current of 50mA. The device utilizes a non-synchronous topology and supports a switching frequency setting up to 1MHz. It is housed in a UCSP50L1C-12 package measuring 1.8x1.5mm with a thickness of 0.57mm. The component functions reliably across an operating temperature range from -40°C to +85°C.

Special Purpose Regulators Feature Summary

• Provides independent ON/OFF control via STBYP and STBYN signals
• Includes circuit protection mechanisms for operational safety

Special Purpose Regulators Applications

• Power supply for TFT-LCD displays
• Portable electronic devices requiring small form factor regulators
• Step-up and inverted output power generation for display panels

Special Purpose Regulators Procurement Notes

Verify the specific suffix E2 indicates compliance with environmental standards such as RoHS. Confirm that the UCSP50L1C-12 package dimensions match the design footprint requirements. Ensure the non-synchronous topology aligns with efficiency targets for the target application. Check availability status as standard grade products may have varying supply chain conditions.

Special Purpose Regulators Selection Notes

Select this component when designing power systems for portable TFT-LCD applications requiring a wide input voltage range of 2.5V to 4.5V. The integrated FET topology reduces external component count compared to discrete solutions. Consider the 50mA output limit and 1MHz switching frequency for noise and size constraints. Verify thermal performance within the specified -40°C to +85°C operating range.
