Overview

Hi-performance Regulator IC Series for PCs Main Power Supply IC for Note PC (Linear Regulator Integrated) BD9524MUV No.
10030ECT06 ●Description BD9524MUV is a switching regulator controller with high output current which can achieve low output voltage (2.
0V～5.
5V) from a wide input voltage range (7V~25V).
High efficiency for the switching regulator can be realized by utilizing an external 3 TM N-MOSFET power transistor.
A new technology called H Reg 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.
For protection and ease of use, the soft start function, variable frequency function, short circuit protection function with timer latch, over voltage protection with timer latch, and Power good function are all built in.
This switching regulator is specially designed for Main Power Supply.
●Features 3 TM 1) 2ch H Reg Switching Regulator Controller 2) Adjustable Simple Light Load Mode (SLLM), Quiet Light Load Mode (QLLM) and Forced continuous Mode 3) Thermal Shut Down (TSD), Under Voltage Lock Out (UVLO), Over Current Protection (OCP), Over Voltage Protection (OVP), Short circuit protection with timer-latch (SCP) 4) Soft start function to minimize rush current during startup 5) Switching Frequency Variable (f=200KHz～500KHz) 6) Power good circuit 7) 2ch Linear regulator 8) VQFN032V5050 package ●Applications Laptop PC, Desktop PC, LCD-TV, Digital Components ●Maximum Absolute Ratings (Ta=25℃) Parameter www.
