Preliminary

Single 12V Input Supply Dual Regulator -

Synchronous-Buck-PWM and Linear-Regulator Controller

uP6161

Features

General Description

The uP6161 integrates a high performance synchronous- Operate with Single 12V Supply

rectified buck controller and a linear-regulator controller.

This part works with a single +12V supply voltage and

delivers two high quality output voltages for both processing

Self-Regulated 9V Drive Voltage

Integrated Boot Diode

Provide Two Regulated Voltages

unit and memory unit. An internal linear regulator provides

optimum 9V drive voltage for efficiency and thermal

management.

One Synchronous-Rectified Buck Controller

One Linear Controller

Both Controllers Drive N-Channel MOSFETs

Smaller Converter Size

The buck controller features internal MOSFET drivers that

supports bootstrapped voltage for high efficiency power

conversion. The bootstrap diode is built-in to simplify the

circuit design and minimize external part count. It

incorporates simple, single feedback loop, voltage-control

with fast transient response.

Excellent Output Voltage Regulation

1.5% for Buck Controller

2% for Linear Controller

Simple Single-Loop Control Design

Voltage-Mode PWM Control

The linear controller drives an externalN-Channel MOSFET

with under voltage protection during both soft start and

normal operation.

Fast Transient Response

High-Bandwidth Error Amplifier

Lossless, Programmable Overcurrent Protection

Uses Lower MOSFET R_DS(ON)

Other features include adjustable operation frequency,

internal soft start, under voltage protection, adjustable over

current protection and shutdown function. With the above

function, this part provides customers a compact, well

protected and cost-effective solution. This part is available

in SOP-14 and QFN3x3 -16L packages.

Adjustable Frequency from 150kHz to 1MHz

Internal Soft Start for Both Outputs

Under Voltage Protection for Both Outputs

including Soft Start Cycle

Applications
