BD8152FVM-TR 数据手册

Single-chip Type with Built-in FET Switching Regulator Series

High-efficiency

Step-up Switching Regulators

with Built-in Power MOSFET

No.10027EBT20

BD8152FVM,BD8158FVM

Description

BD8152FVM,BD8158FVM are the 1-channel step-up switching regulator which builds in the low voltage FET. Input voltage

is 2.5 V to 5.5 V (BD8152FVM), 2.1V to 5.5V(BD8158FVM) realizing the low consumption power. High accuracy feedback

voltage 1% is established and the brightness dispersion of TFT-LCD panel is suppressed.

Features

1) Current mode PWM system

2) Input voltage is 2.5 V to 5.5 V (BD8152FVM), 2.1 V to 5.5 V (BD8158FVM, providing the low power input)

3) Switching frequency is variable as 600 kHz/1,200 kHz.

4) Built-in 0.25 Ω power switch

5) Feedback voltage 1.245  1%

6) Built-in under-voltage lockout protection circuit

7) Built-in overcurrent protection circuit

8) Built-in thermal shutdown circuit
