ISL6413
Triple Output Regulator with Single
Synchronous Buck and Dual LDO
The ISL6413 is a highly integrated triple output regulator
which provides a single chip solution for wireless chipset
power management. The device integrates high efficiency
synchronous buck regulator with two ultra low noise LDO
regulators. The IC accepts an input voltage range of 3.0V to
3.6V and provides three regulated output voltages: 1.8V
(PWM), 2.84V (LDO1), and another ultra-clean 2.84V
(LDO2).
The Synchronous current mode PWM regulator with
integrated N- and P-channel power MOSFET provides pre-
set 1.8V for BBP/MAC core supply. Synchronous
rectification with internal MOSFETs is used to achieve higher
efficiency and reduced number of external components.
Operating frequency is typically 750kHz allowing the use of
smaller inductor and capacitor values. The device can be
synchronized to an external clock signal in the range of
500kHz to 1MHz. The PG_PWM output indicates loss of
regulation on PWM output.
The ISL6413 also has two LDO regulators which use an
internal PMOS transistor as the pass device. LDO2 features
ultra low noise that does not typically exceed 30礦 RMS to
aid VCO stability. The EN_LDO pin controls LDO1 and
LDO2 outputs. The ISL6413 also integrates a RESET
function, which eliminates the need for additional RESET IC
required in WLAN applications. The IC asserts a RESET
signal whenever the V
IN
supply voltage drops below a preset
threshold, keeping it asserted for at least 25ms after V
IN
has
risen above the reset threshold. The PG_LDO output
indicates loss of regulation on either of the two LDO outputs.
Other features include over current protection for all three
outputs and thermal shutdown.
High integration and the thin Quad Flat No-lead (QFN)
package makes ISL6413 an ideal choice to power many of
todays small form factor industry standard wireless cards
such as PCMCIA, mini-PCI and Cardbus-32.
