Overview
The ZXLD1101ET5TA is a PFM inductive boost converter designed for driving white LEDs. It operates from an input supply of 2.5V to 5.5V and provides an adjustable output current up to 50mA. The device supports a maximum output voltage of 28V and features a switching frequency up to 1MHz. Quiescent current is typically 60μA, reducing to less than 500nA in shutdown mode. It is housed in a TSOT-23-5 package with a 1mm height profile.
Feature Summary
- Integrates internal switch and peak current sense resistor for low external component count
- Supports true analog dimming via PWM control signal applied to the Enable pin
- Contains internal PWM filter components to ensure flicker-free output
Applications
- Mobile phones
- Digital cameras
- LCD modules
- Portable internet appliances
Procurement Notes
Verify the specific suffix ET5TA against official Diodes Incorporated documentation to confirm the TSOT-23-5 packaging and reel specifications. Ensure compatibility with the required input voltage range of 2.5V to 5.5V for your target LED configuration. Cross-reference the datasheet revision date to validate thermal and electrical parameters before finalizing procurement orders.
Selection Notes
Select this component when designing circuits requiring a compact solution for driving 2 to 4 series-connected white LEDs from a Li-Ion cell or up to 8 LEDs from a 5V supply. The integrated switch and low quiescent current make it suitable for battery-powered portable devices where space and power efficiency are critical constraints.
Part Context
This part belongs to the ZXLD1101 family of adjustable LED drivers manufactured by Diodes Incorporated. It is specifically engineered as a high-efficiency boost converter optimized for mobile and consumer electronics applications. The device simplifies design by incorporating necessary control logic and filtering within the single IC package.
Replacement Considerations
Consult official Diodes Incorporated substitution guides for verified alternatives. Do not assume functional equivalence with other ZXLD series parts without verifying pinout and electrical parameter alignment.
