Overview
| Topology | Flyback Converter |
| Input voltage | 25-450 V |
| Output 1 | 13 V / 0.25 A |
| IC revision | A |
Description
HV9120 and HV9123 are Switch-Mode Power Supply (SMPS) controllers suitable for the control of a variety of converter topologies, including flyback and forward converter. Using an internal, high-voltage regulator, HV9120 and HV9123 can derive a bias supply for starting-up and powering a converter from a variety of power sources, such as a 12V battery or the rectified AC (230 VAC) line. HV9120/HV9123 controllers include all essentials for a power-converter design, such as a bandgap reference, an error amplifier, a ramp generator, a high-speed PWM comparator, and a gate driver. A shutdown latch provides on/off control. Device power consumption is less than 6 mW when shutdown.HV9120 offers 50% maximum duty, and HV9123 offers nearly 100% duty.
Features
- 10 to 450V Input Voltage Range
- <1.3 mA Supply Current
- ≤1 MHz Clock
- Maximum Duty Version
- HV9120: 49%
- HV9123: 99%
Typical applications
- High Density Power Supplies, Offline High-Frequency Power Supplies, Extra Wide Load Range Power Supplies, Universal Input Power Supplies, Very High Efficiency Power Supplies
