Key Features
- Generates adjustable negative output from -2 V to -15 V directly from a 2.7 V to 5.5 V positive supply using a single inductor
- Current-mode PWM control for fast transient response and simplified loop compensation in inverting converter designs
- Compact 10-pin MSOP package enabling negative rail generation in space-constrained portable and handheld systems
Applications
The TPS63700DRCT is used in portable instruments, LCD bias supplies, and op-amp dual-rail systems where a negative voltage must be derived from a single positive supply such as a 3.3 V or 5 V rail. Its adjustable -2 V to -15 V output range suits OLED display drivers, audio amplifier bias circuits, and analog front-ends requiring a symmetric bipolar supply. The device's 2.7 V minimum input makes it compatible with single Li-ion battery systems operating down to near end-of-discharge.

Frequently Asked Questions
How does the TPS63700DRCT generate a -15 V output from a 3.3 V positive supply in a portable instrument?
The TPS63700DRCT uses a current-mode PWM inverting topology with an external inductor to transfer energy from the 2.7 V to 5.5 V positive input and deliver it at a regulated negative output adjustable from -2 V to -15 V. The duty cycle is controlled to maintain the programmed negative output rail, making it possible to derive -15 V for op-amp rails or LCD bias from a single 3.3 V or 5 V supply without a separate transformer.
For an OLED display bias requiring -5 V, how does the TPS63700DRCT's adjustable output simplify the design?
The TPS63700DRCT allows the output voltage to be set anywhere between -2 V and -15 V using two external resistors, so a designer can target exactly -5 V for an OLED bias supply from a 3.6 V Li-ion cell. This eliminates a separate negative supply IC for the display, reducing the bill of materials and PCB area while the current-mode PWM control maintains stable regulation across the 2.7 V to 5.5 V input range.
When is the TPS63700DRCT a better alternative to a charge-pump inverter for generating a negative rail?
Charge-pump inverters are limited to low output currents (typically below 100 mA) and cannot easily provide outputs below -5 V without cascading stages. The TPS63700DRCT's inductor-based topology supports higher output currents and a wider -2 V to -15 V output range from a 2.7 V to 5.5 V input, making it preferable for op-amp dual-rail supplies or precision ADC front-ends needing stable negative voltages at tens to hundreds of milliamperes.
