Product Description
The CM9156A is an efficient, 1.5x switched capacitor
(charge pump) regulator ideal for white LED applica-
tions. It has a regulated 4.5V, 120mA output, capable
of driving up to six parallel white LEDs. With a typical
operating input voltage range from 3.0V to 6.0V, the
CM9156A can be operated from a single-cell Li-Ion
battery.
It features an efficient, 1.5x charge pump circuit that
uses only two 1.0µF ceramic bucket capacitors and two
small capacitors for VIN and VOUT. The CM9156A
offers a selectable switching frequency of 8kHz, 32kHz,
262kHz, or 650kHz. The LED brightness can be
adjusted by applying a PWM signal on the ENA pin.
The CM9156A output voltage is regulated to 4.5V, ±
5% over the line and load ranges. Up 180mA of output
current is available. The proprietary design architecture
maintains high efficiency (> 80%), and at low VIN pro-
vides longer battery life. With a high VIN, or when the
adapter is powered, it provides cool reliable operation.
It offers low output voltage ripple, typically less than
50mV. Internal over-temperature and over-current
management provide short circuit protection.
The CM9156A is packaged in either a space saving
10-Lead TDFN or 10-Lead MSOP package. It can
operate over the industrial temperature range of -25°C
to 85°C.
