BD8151EFV_09 Overview

1.5 A SWITCHING REGULATOR, 1440 kHz SWITCHING FREQ-MAX, PDSO20

Power Supply IC Series for TFT-LCD Panels
Single
-channel Source Voltage
Output Power Supply + Gamma Buffer Amp ICs
BD8151EFV,BD8157EFV
No.09035EBT11
●Description
The BD8151EFV,BD8157EFV power supply IC are designed for use with TFT-LCD panels. It incorporates a built-in source
voltage step-up switching regulator and gamma correction buffer amp. The combination of a source power supply and
gamma correction buffer on a single chip delivers significant cost savings.
Compatible with input voltages from 2.5 V to 5.5 V (BD8151EFV), 2.1 V to 4.0 V (BD8157EFV), the IC supports low-voltage
operation and reaches over 85% efficiency with a 2.5 V input, contributing to low power consumption designs.
●Features
1) Single-chip implementation of a source power supply and gamma correction buffer
2) Support for low-voltage operation, with input voltages from 2.5 V to 5.5 V (BD8151EFV)
2.1 V to 4.0 V (BD8157EFV)
3) Built-in 1.4 A, 0.2
low-voltage FET
4) Switchable step-up DC/DC switching frequencies: 600 kHz/1.2 MHz
5) Current mode PWM control
6) Under-voltage lockout protection circuit
7) Built-in overcurrent protection circuit
8) Built-in thermal shutdown circuit
●Applications
Satellite navigation systems, laptop PC TFT LCD panels
LCD monitor panels
