KEY FEATURES
High-Side
Buck –
Direct
Feedback
1. Output referenced to input
2. Positive output (V
O) with respect to -VIN
3. Step down – V
O < VIN
4. Low cost direct feedback (±10% typ.)
High-Side
Buck –
Optocoupler
Feedback
1. Output referenced to input
2. Positive output (V
O) with respect to -VIN
3. Step down – V
O < VIN
4. Optocoupler feedback
- Accuracy only limited by reference
choice
- Low cost non-safety rated opto
- No pre-load required
5. Minimum no-load consumption
Low-Side
Buck –
Optocoupler
Feedback
1. Output referenced to input
2. Negative output (V
O) with respect to +VIN
3. Step down – V
O < VIN
4. Optocoupler feedback
- Accuracy only limited by reference
choice
- Low cost non-safety rated opto
- No pre-load required
- Ideal for driving LEDs
Low-Side

High-Side
Buck Boost –
Direct
Feedback
1. Output referenced to input
2. Negative output (V
O) with respect to +VIN
3. Step up/down – V
O > VIN or VO < VIN
4. Low cost direct feedback (±10% typ.)
5. Fail-safe – output is not subjected to input
voltage if the internal MOSFET fails
6. Ideal for driving LEDs – better accuracy
and temperature stability than Low-side
Buck constant current LED driver
