BD9528MUV - Main Power Supply ICs

General Description

BD9528MUV is a 2ch switching regulator controller with high output current which can achieve low output voltage (1.0V～ 5.5V) from a wide input voltage range (5.5V～28V).

High efficiency for the switching regulator can be realized by utilizing an external N-MOSFET power transistor.

Key Features

  • 2ch H3REGTM DC/DC Converter controller 2) Adjustable Simple Light Load Mode (SLLM), Quiet Light Load Mode (QLLM) and Forced continuous Mode 3) Thermal Shut Down (TSD), Under Voltage LockOut (UVLO), Over Current Protection (OCP), Over Voltage Protection (OVP), Short circuit protection with 0.75ms timer-latch (SCP) 4) Soft start function to minimize rush current during startup 5) Switching Frequency Variable (f=200kHz～500kHz) 6) Built-in Power good circuit 7) Built-in 2ch Linear regulator (5V/100m.

Hi-performance Regulator IC Series for PCs Main Power Supply ICs for Note PC (Linear Regulator Integrated) BD9528MUV No.10030EAT26 ●Description BD9528MUV is a 2ch switching regulator controller with high output current which can achieve low output voltage (1.0V～ 5.5V) from a wide input voltage range (5.5V～28V). High efficiency for the switching regulator can be realized by utilizing an external N-MOSFET power transistor. A new technology called H3RegTM(High speed, High efficiency, High performance) is a Rohm proprietary control method to realize ultra high transient response against load change. SLLM (Simple Light Load Mode) technology is also integrated to improve efficiency in light load mode, providing high efficiency over a wide load range.
