Overview
| Topology | Buck Converter |
| Input voltage | 8-18 V |
| Switching frequency | 100-2500 kHz |
| Output 1 | 24 V / 2 A |
Description
This EVK uses a non-synchronous rectifying boost DC / DC controller IC BD9615MUV-LB to output 24V from an input voltage of 8V to 18V. BD9615MUV-LB accepts a power supply input range of 3.5V to 60V. The output voltage can be set with an external resistor. An external resistor can adjust the switching frequency from 100kHz to 2500kHz. It reduces the total mounting area because it can operate at extremely high switching frequency. In addition, it has an external clock synchronization function to perform noise management. BD9615MUV-LB has Thermal Shutdown (TSD), Over VoltageProtection (OVP), UVLO Control Function by External Resistors, and Over Current Protection (OCP) to prevent damage caused by various abnormal modes.
Features
- Long Time Support Product for Industrial Applications
- Wide Input Voltage Range: 3.5V to 60V
- Frequency Setting Function: 100kHz to 2500kHz
- External Clock Synchronization Function
- Soft Start Time Control Function
- ON/OFF Control by the EN Pin (Standby Current 0μA)
- Over Voltage Protection Function by an Independent Pin
- Normal/Abnormal Signal Output by the PGDB Pin
- UVLO Control Function by External Resistors
- MAX DUTY Change Function: (50%/90%)
- High Power Small Package (VQFN16KV3030)
Typical applications
- LED lighting
- Industrial distributed-power applications, OA equipment
- General consumer devices with 12V/24V lines, Entertainment equipment
