Datasheet

Switching Regulator with external FET

3.9 to 30V, 2ch Synchronous Rectification

Step-Down Controller

BD9015KV-M BD9016KV-M

General Description

Key Specifications

Input voltage range:

Output voltage range:

The BD9015KV-M and BD9016KV-M are high perfor-

mance synchronous rectification switching controllers

with wide input range and dual channel output.

The synchronous rectification method comes with high

efficiency making controller ideal for eco-designs(low

power consumption) of numerous electronics.

All channels have enable pins, soft start functionality and

power good outputs. Startup and shutdown can be

controlled independently.

3.9 V to 30 V

0.8 V to 10 V

Accurate voltage reference:±1.5%(-40°C to +105°C)

Switching frequency:

Shutdown current:

250 kHz to 550 kHz

0μA (Typ)

-40°C to + 105 °C

Operating temperature range:

Package

W (Typ) x D (Typ) x H (Max)

VQFP48C

9.00 mm x 9.00 mm x 1.60 mm

An integrated PLL circuit can be synchronized to an

external 250kHz to 600kHz clock signal.

Features

■ N channel MOSFET direct drive

■ Synchronous rectification for increased efficiency

■ Acceptable Low ESR ceramic capacitor at output

■ Integrated PLL circuit for external synchronization;

250kHz to 600kHz

■ Current mode control

■ High side MOSFET current sensing

■ Pre-bias functionality

VQFP48C

■ Independent ON/OFF control for all channels

■ At Max Duty the oscillation frequency is slowed down

to 1/5, reducing the input/output voltage difference.

■ Low voltage and over voltage detection circuit at all

outputs

Applications

■ Car audio, Car navigation

■ LCDTV, PDPTV, DVD, PC, etc..

When the over voltage is detected, the L-side FET is

OFF (BD9015KV-M). The L-side FET is ON

(BD9016KV-M).

Low side FET is ON (BD9016KV-M)

■ Power good indicator pin (PGOOD)

■ Integrated overcurrent protection with self recovery.
