Positive and Negative Output DC-DC Converter

General Description

Features

The CC100 device is a dual-output DC-DC converter

supply that generates a positive output up to 15 V and a

negative output down to –15 V. The converter maintains

low output voltage ripple. Typically, the maximum output

currents are in the 200- mA to 500-mA range, depending

on input voltage to output voltage ratio and the current

limit option. The combined (VPOS and VNEG) efficiency

◼

Input voltage range: 2.7-V to 5.5-V

AEC-Q100 Grade 2 Qualified

VPOS positive boost converter output



Adjustable output: up to 15 V

Switch current limit 2 A

Conversion efficiency: up to 89%

◼

VNEG negative inverting buck-boost converter

output

reaches 85% to keep systems cool or achieve a longer

battery-on time. The input voltage range of 2.7 V to 5.5 V

allows the devices to be powered from batteries or from

fixed 3.3-V or 5-V rails.



Adjustable output: down to –15 V

Switch current limit 2 A

Conversion efficiency: up to 81%

◼

Control output for external P-channel FET

Supports complete disconnection from battery

1-µA shutdown current

The converter operates with a fixed frequency PWM

control topology and, when operating in power save

mode, uses a pulse-skipping mode at light load currents.

It operates with only 500-µA device quiescent current.

Individual enable inputs for flexible output

sequencing

Independent enable pins allow flexible power-up and

power-down sequencing for both outputs. The positive

and negative outputs operate independently, allowing for

non-symmetrical output voltages and currents.

◼

Protection features



Over voltage protection at VPOS and VNEG

Input under voltage lockout

VPOS and VNEG SCP

Thermal shutdown protection

The converter has an internal current limit, over voltage

protection, and a thermal shutdown for highest reliability

under fault conditions. The converter is available in a

4-mm × 4-mm QFN-24 package. The solution size is

small with a minimum switching frequency of 1.25 MHz

for smaller inductors and few other external components

required.

4-mm × 4-mm QFN-24 package

Application

◼

LCD and AMOLED displays (approx. 4" to 17")



Personal electronics (notebook, monitor,

gaming)



Building automation (elevator, thermostat)

Healthcare, fitness, EPOS, industrial HMI, test
