Introduction
ME3121 is a high-efficiency synchronous rectification buck DC-DC converter IC with an input voltage up to 40V. It integrates two low on-resistance NMOSFET power switches — low-side switch RDS(on) of 170mΩ and high-side switch RDS(on) of 410mΩ — supporting up to 1A load current. Under light load, the IC operates in PFM mode; under heavy load, it operates in quasi-PWM mode with continuous current at a switching frequency of 1MHz. The IC employs an adaptive constant on-time control architecture for fast load transient response.
Features
- Input voltage range: 4.7V ~ 40V
- Shutdown current: 8uA
- Quiescent current: 120uA
- On-resistance: low-side 170mΩ, high-side 410mΩ
- Switching frequency: 1MHz
- Reference voltage: 0.6V ± 2%
- Cycle-by-cycle current limiting: peak current limit 1.9A, valley current limit 1.4A
- Output short-circuit protection: hiccup mode
- Over-temperature protection: 160°C
Applications
- Set-top box
- LCD TV
- DSL modem
- Digital TV
