Primary-Side Power Control IC for LED Lights

Monolithic IC MM3460XF
Outline
This IC is a PFC switching power control IC for LED lights.
It uses a one-converter system into which a PFC (Power Factor Correction) circuit and an AC-DC converter
become integrated. Compared to a regular two-converter, a high-efficient configuration can be achieved
due to reduction in the number of parts and little power loss. In addition, there is me as the protection
setting that built-in specialized input low voltage, overvoltage protection, output overvoltage with a delay,
a short protection circuit in for one-converter / for LED lights as a protection circuit and I compare it with
conventional PFC-IC and can set it with few part marks.
Moreover, the consumption of start-up current and current during operation are lowered for low standby
mode electricity.
This IC uses SOP-8 package and supports ow conditions.

Features
Limits for harmonic current emissions (one-converter system)
PF 0.99 (reference value)
High efciency: 88% (reference value, at rated load)
Reduction in the number of parts by not using an active lter (PFC) control circuit
Longer life can be achieved by not using the primary electrolytic capacitor
1. High voltage input :
28V
2. LED output :
5~60W
3. Critical conduction current mode
4. Built-in input UVLO, overvoltage protection (28V Zener) circuits
5. Built-in output (FB) short, overvoltage protection circuits (with a delay feature)
This Function is original protection
6. Start-up current (30µA), current during operation (1mA)
